SolidWorks Flow Simulation - Transient Manifold Airflow

This is an example of how to set up time-dependent pressure drops on cylinder inlet ports to simulate engine intake manifold valves opening and closing at each cylinder port. SolidWorks Flow Simulation, 2009.

It is "fake" data. It is just an upside-down sine function generated in Excel, scaled from atmospheric pressure to some arbitrary value to cause the air to exit the chamber. It is only for demonstration purposes.

Good video, however using pressure differentials alone does not seem like it will provide data that is accurate? Valves function as a barrier so you have a pressure differential being controlled by a barrier which will allow for wave reflection off the valves. This will have a significant impact on the flow characteristics. Have you done further modeling to deal with this issue?

dude .. How in the planet hell did you create this Animations ???? every time i choose flow trajectories and try to create a scenario animations all i get is a non-moving arrows or lines with changes in the color .. the scenario works good only with "3D-plot & cut-plan" ..... so i was forced to creat a simulation for every iteration and then put them together with a movie editing software ... you can see it among my videos

Yes, generate a cut plot (or some other plot), right-click on that and choose "animation", then use the "Wizard" button and choose option "Scenario" to load the 20 files all at once. Then insert a control point on the time line of the plot and stretch to the end.

Here is a video we did for GoEngineer's YouTube channel: youtube.com/user/goengineer

Good luck.

@flexus1988

i have the same problem if sig is around an explanation of how this is done would be great.

as having problems getting all the data generated and only get results for the end time point

@Sigsite723 Thanks a lot

[Vari86]

Where can I get that Excel file with all the data needed? Thanks a lot.

such a loose video
