 My name is Yanto Cannon and I'm a fourth year PhD student. So I look at fluid mechanics, the behaviour of anything that flows. Yeah, so this is a comparison of two different types of droplets in a channel. So above we have droplets which are not able to coalesce. So when they encounter each other, they will just basically bounce off each other. Below we have droplets which easily coalesce. So when two droplets come near each other, they will merge to form one. And they can also break up. In the top case, this is like water with oil droplets inside. And then we added soap. The soap would assemble on the interface of these droplets and it would have this effect of preventing coalescence and break up. So in the lower image, this is like we have clean water and we add pure oil into the water. Going from the numerical data of the flow to the image that you see is less than a minute. So we want to know how easily does the fluid move through the channel. And this is important for medical reasons because it's fairly similar to blood flow in the artery or also to industry when you want to pump large amounts of fluid through pipes. And we do simulations because we can easily measure the flow at every point inside the pipe.
