 Thank you very much. This is a really important series here, Associate Professor Celebration, and we organize about three per year from Arvin's office. So he is traveling right now to a global location for the wonderful work he's also doing on the side with USAID and so on. So you've got the substitute. I hope you can bear with me for two minutes just to show the deep appreciation for the tenure system here and a huge congratulations to those who received tenure in recent years. We started this as one of the feedback from the faculty members and graduate students postdocs is that we should feature our recently tenured associate professors and congratulate them on their early retirement. I mean on their having the platform to dream big, aim higher and think outside of the box and to maximize the benefits of this highly unusual system in the labor market called tenure that we hold with great pride and it's not easy to receive tenure at Purdue Engineering. We would love to give them the opportunity to share with us what they did in research, in teaching, in engagement that got us where they are today. So with that I will hand it over to the two month old head, the brand new head of the School of Aeronautics and Astronautics, my great colleague and great leader for the AAE school here, Bill Crossley, to introduce the first speaker today. Thank you, Bill. Thank you, Mon. Well, welcome everybody. It's a neat opportunity to be here. I had the pleasure of introducing my colleague Dr. Sally Bain and this is called the Celebration of Associate Professors and it really is a celebration because while I'm two months and five days into my term as head, Sally is just basically two months because you started it, Associate Professor, just in August here. So this really is a celebration for Sally. She is recently promoted with tenure. Sally did her undergrad at the University of Virginia and then moved from Virginia out to Pasadena, California and did both her masters and PhD out at Caltech, did a short post-doc stint there, then came and joined us in 2011 here at Purdue. She's going to talk about her research. I'm not going to give those highlights. I just wanted to put in a little personal spin here. I had the pleasure of working with Sally on a project with the Boeing company a few years ago. It was a very large project to try to merge computational data about aerodynamics and experimental data because of Sally's role in our undergraduate aerodynamics laboratories, she does a lot of work in the large wind tunnel and so she was generating some of our experimental data for that. Fun project, got one of your students hired at Boeing and I keep running into Monion. She keeps doing better and better. So another example of Sally's great mentorship for her students and one of the fun things is that a few years ago we had celebration of faculty careers and I was introduced as one of the young old guys and so now I get introduced Sally as one of the young middle-aged people. Does that work? I'm there, yeah. I'm still one of the old guys. So with that let me introduce Professor Sally Bing. Okay, so this is quite a turnout. I have to say a little nerve-wracking. I'm going to assume you didn't all come to see me. So first of all it is really a great pleasure to be able to still be here, give this presentation and to be able to have a career like this at such a wonderful institution. So I didn't come up with a creative title for my talk and I probably have too many slides so I'll just get right to it. Bill already talked about my background. I got my Bachelor's in Aerospace Engineering at UVA, had to do an undergraduate thesis there because we had a very small program that really got me interested in research and made me realize like this is absolutely what I want to do. I had a great mentor there who helped me get an NSF fellowship which took me to Caltech where I did my MS and PhD and I did a one-year postdoc there while I looked for a job and then came here in 2011 and now I'm very excited to be able to continue my career here as an associate and hopefully someday a full professor. So I wanted to touch quickly on my research, teaching and service since those are like the three prongs. As usual I put too many slides for research so I'll just try to go through them quickly. So my research interests really fall into three areas, experimental combustion, that's the area that I did my PhD in so I still do some of that work here. I always have to show off this picture here of this giant explosion coming out of the end of my 20-foot explosion tube at Sandia because it's a unique facility and the slow-mo guys even came and recorded a video of us annihilating a computer which I will play at the end of the presentation if there's time. And then the other two areas that I spend most of my time on really are plasmas for aerospace applications and then closely tied to that are plasma and flow diagnostics and that's an area that I started becoming interested in when I was at doing my PhD because I got a little bit of exposure to plasmas there but I quickly identified this is a cool area and so when I came to Purdue I really wanted to focus on that and sort of establishing my own way in that area and so far so far doing okay apparently. So I'm just going to really briefly touch on these but first what is a plasma so I apologize if you all already know this but I like this picture because people always say you know I say I work in plasmas they go what is okay plasmas that's my husband thinks it sounds cool because he watches sci-fi and there's lots of plasma drives and plasma warp cores and everything but I don't work in that kind of plasma which might be like way up there. So they basically a plasma is just an ionized gas with positive ions and free electrons and we can have lots of different kinds of plasmas depending on how energetic the electrons are what the gas temperature is and how many charged particles we have. So I decided to work in the area of what we call cold plasmas which you can see there with the little circle they are you know 10,000 degrees or less about there might be some colleagues who are I see one here who might disagree but and these are really interesting plasmas for a variety of reasons and the reason that I'm interested in these is because these plasmas basically when they're cold what we mean is they can be cold literally they can be room temperature but the electrons are much much hotter they're very energetic so you would generate these by applying a very large electric field so that's what I do and what happens is these energetic electrons create excited molecular states they dissociate molecules they ionize molecules so you have all these really active excited energetic particles in your gas and they can also locally heat the gas and so this actually opens the door for a lot of really interesting interactions between these plasmas and surrounding gases or materials so and so they're very chemically active they can provide localized rapid heating and they can also provide hydrodynamic effects and plasmas because it's all electronics we can turn them on and off practically instantaneously we can operate them at almost any frequency you can imagine we can generate them with no moving parts so they really are an interesting and promising candidate for a lot of applications that require tailoring of chemistry for instance or really fast response time so what has been really helpful to me tremendously helpful is the develop the establishment of the cold plasmas team here at Purdue because this brought together several very distinguished faculty who work in this cold plasmas area into this team which provided me a lot of really valuable mentorship and advocacy for which I'm very grateful and so this just shows like the kind of the range of things that we do on the cold plasmas team I work primarily in this plasma aerodynamic and combustion control but we have members that work there's a couple in the audience who work on everything from treating tumors to making plasma antennas and so this was a really important thing for me here in helping me to really advance in in the field is having these having these mentors for me okay so I know I'm already five or six minutes in so I'm good okay so um just a couple slides showing the kind of things I do so in the plasma and flow diagnostics my goal here at Purdue has been to bring together my capabilities as well as other folks capabilities and you can see here there's a whole big list of plasma measurements and so I do a lot of these myself I'm collaborating with other faculty with expertise in more advanced diagnostics and how to apply them to plasmas because I want to create here at Purdue like an in-house complete characterization team that I don't think exists anywhere else and then I do a lot of flow diagnostics this is actually a spark that we're generating between the electrodes and as you can see it generates a shockwave and a rather complex flow field so we do things like particle image velocity symmetry schlieren methods to um measure the effect of this flow and so here you're seeing uh there's not plan anymore but you're seeing vorticity contours so um this is important particularly for aerodynamic and combustion control um and then two uh two slides here on the two applications I'm most interested in one is plasma flow control particularly of supersonic flows so here this is a wedge in a supersonic Mach 2 flow we generate plasma here and this is the baseline flow with a shockwave and a separation zone and you can see in this little video when we turn the plasma on the whole structure moves up quite significantly okay you know so what but that's what's significant is that this is a high speed compressible flow that we are affecting with about a watt of electrical power so this is a rather new area but um along with uh collaborations with my colleagues we are really focusing on understanding what is the coupling that allows us to have this intrinsic control um and we hope to extend this also to hypersonic flows which hypersonics is a big initiative here at Purdue um and then plasma assisted combustion the idea is to use plasma to alter combustion these are not mine these are pictures from a few other projects that got me really interested in this where you can see that when we turn the plasma on the flame structure changes significantly so what I've been doing here is developing capabilities state-of-the-art capabilities to study plasma assisted combustion so one is this atmospheric pressure burner where we make a swirl flame um kind of like a gas turbine flame but uh lower power and we apply a plasma at the exit and we try to affect the combustion dynamics and so just a little video that's what the flame looks like we generate a plasma which looks like a fireball and try to affect the particularly the stability and then um in that kind of the outlook for that research is um in collaboration with a colleague in my department we've um built this high pressure gas turbine combustor with plasma actuation where we're going to actually try to demonstrate that we can affect combustion dynamics at gas at um engine relevant conditions and we already have some industry that are giving us some injectors and saying why don't you give it a try so um that the outlook for that is is really promising and this is a one-of-a-kind facility nobody has something like this so let's hope it works or I hope it works um I don't uh so quickly so I talk too much about research like everybody does um but teaching since I came here I I've been teaching the fluid mechanics and aerodynamics lab courses in our department so the three the fluid mechanics lab is required course so I get to to teach at least 250 students a year um in that class um this is a picture of our teaching lab where we have all kinds of wind tunnels and experiments for the students to get some real world experience um as far as that goes I I I'm really looking forward to hopefully uh helping to kind of revolutionize the way that we do our lab classes because like many departments we have a booming enrollment and I look at lab classes as a chance to give students real practical experience in things that their future employers are going to want to see um so I really hope to stay actively involved with the lab courses um and to hopefully we have some plans to implement some virtual labs to change the structure around um so that uh we can continue to give our students the best kind of laboratory um education we can I also teach graduate aerodynamics um which allows me uh we have a large uh undergrad enrollment there too so and I also teach that as a distance course so I've been able to um meet a lot of students from from outside of Purdue as well through that and also that's really forced me to work on my teaching style because if you're teaching to people 500 miles away you know you don't want them to turn you off so um so that's that's really been interesting and I I hope to continue to improve the curriculum there also to try to um teach them really what like we have a lot of students who are out there working and I want to teach them things that they'll actually use when they go back to the office and finally last slide um service within Purdue um different a few different committees I I enjoy doing the horizons mentoring program for first generation college students I've done that nearly every semester I find it really rewarding um I also do a lot of um as Bill said we have a a big wind tunnel the Boeing wind tunnel and I I enjoy helping a lot of student groups with doing their designing and implementing experiments in that tunnel because they really seem to enjoy it um and then last but not least outside Purdue I just listed one thing because my main activities are with a technical committee in AIAA which um once again my mentor has helped me to get a seat on that committee and I've become extremely active in in or they've appointed me active uh as a chair of every award subcommittee uh apparently I'm not sure how it happened but it's been great for my um networking and my visibility um because I uh it really gives me a chance a good excuse to reach out to people and start conversations because I have to ask them to review papers or to session chair so that's been a really wonderful thing I hope to I plan to continue doing that and I also hope as an associate professor to get more involved at the college and university level on on um in the service aspect so I think I'm out of time so that's it oh here let's see I'll just I'll just play this so nobody asks me any questions I have oh whoops I meant to mute it but okay yeah there we go highly scientific I'm sure sandia well sandia was delighted that we used their uh research team for that every graduate students dream about two months before dissertation defense is like this is not boom yes it's yeah so I always have to show that I think we do have a few seconds for not seconds a few minutes maybe for questions that we started a little bit late I think I'm supposed to walk around and make sure you speak into the microphone since we're recording that so do people have questions for sally also out of plug just really quick that uh we do want you in the aerodynamics lab as long as you're happy doing that that's a huge part of our curriculum that's as most schools have grown in size that's one of our pinch points is how do we get all of our students that exposure and sally and her team of teaching assistants have really helped us pull that off you have questions for sally yes good you don't need it they need it as everybody goes to goes through this uh in your process how do you balance your family and work um that's a great question I I do I do have two little boys um it was all I could do not to put a picture of them up here because I'm that embarrassing mom um I had them both while I was here they're two and five um I just made a decision early on that uh I would be as productive as I possibly could while I was in the office and that uh you know during certain hours um I was just going to put my phone away and I was going to interact with my kids and I tried to spend most of my time with them on the weekends um if I have a deadline of course all bets are off but uh you know and I'm sure it's affected my productivity negatively but the department you know I found colleagues are very supportive because they recognize you know if you uh if you get tenure but you don't see your kids right as kind of a you you kind of lost so I just try to yeah so I mean I I just made a decision that I was going to put them first after working hours unless I had a proposal to write and then yeah so now that there have been a faculty for so long if you can go back and give an advice to yourself 10 years ago and while you are in graduate school what advice would you give yourself when I was in graduate school or when I first started my job sorry either either or um well I think it applies everywhere um ask for ask for what I need um I I uh same thing in graduate school it took me a long time to learn to ask my advisor or other graduate students for what I needed I just did a lot of nodding like okay got it and I had no idea what anybody was talking about and then when I got here I had no idea what I was doing right fresh out of graduate school so I think going to people and saying I need help I need advice on this will you read this for me am I doing this right it took me a really long time and I'm still not very good at it so I think um you know uh ask for mentorship ask for you know um that that would have been the number one thing I would tell myself maybe one more question for so what's the coolest experiment you guys do in in your aerodynamics labs to you as the instructor to me um I let's say I really like this we have a little supersonic wind tunnel that's very annoyingly loud if you ever walk by the lab um you can probably hear the squeal um but I I love that because we we we put in like a wedge model and if you guys anybody you know supersonic flow you're going to get shock waves and expansion waves and we just set up some very simple optics and all of a sudden they can see the shocks and expansions and students always always find that really really neat because it's something that you can't see with your eyes you just sort of write down on paper then all of a sudden they're doing an experiment there they are they can see them and not only that but they actually agree the answers agree very well with theory so it's one of those cases where we can tell them like this is actually you know you know what we're teaching you in the lecture is actually true so that's that's my favorite one the students seem to enjoy that one the most please join me and let's celebrate sally bane
