CFD simulation of vortex shedding

[Lavabug]

Interesting, do you use this for aeronautical engineering? I'll probably be taking a CFD course in grad school (physics).

hello.. how to make this video actually?

[slffea]

SLFCFD uses OpenGL to create the individual frames, then ffmpeg to compile the frames into animation.

How accurate is this simulation compared to an real enviroment?

[slffea]

I based my software on the paper, "A numerical study of vortex shedding from rectangles", by Davis, R. W., and E. F. Moore. There are comparisons with actual experimental data in terms of the Strouhal number in the original paper. My results were not quite as good as theirs, but were of the same order as the experimental results.

Interesting. Which turbulence model is this?

[slffea]

It's actually based on laminar flow. The code will remain

stable for Re=50,000 and beyond, but you have probably crossed over into turbulence by then and will need a more sophisticated code.

9000 views and no comments?

I will, How do i get thtis? I have cuda.

There were probably no comments because most people watched this video embedded from my website. You can get the code there as well. Unfortunately I can't link from here. It would also be easier if you have Linux/Unix.
