Von Karman Vortex Street

Animation of Von Karman Vortex Street created by 1, 2 or 3 cylindrical obstacles. The flow is made visible through violet dye or given different colors for clockwise (yellow) and counterclockwise (green) vortices. Fluid is simulated by solving Navier-Stokes equations with "stable fluids" method of J. Stam adapted for GPU implementation and extended with vorticity confinement http.developer....

Put obstacles arranged in a logarithmic spiral pattern in an airstream, and see what happens!

This is scientifically valuable -- can you share your code?

[@physicsgraphics954]

Code is not clean enough to share it)) I used this article developer.download.nvidia.com/books/HTML/gpugems/gpugems_ch38.html

[@rezaziazi]

Hi did you publish these results in a paper? Could you please add the link to the paper if you had published it?

[@physicsgraphics954]

I used this article to code this developer.download.nvidia.com/books/HTML/gpugems/gpugems_ch38.html

[@physicsgraphics954]

I did not publish these results. It is famous fenomena)

Hi., what kind of software is been used for the visualisations?

[@physicsgraphics954]

Hi! For the computations and visualisations power of OpenGL (GLSL) was used.

[@gregliako7995]

sorry i didnt ment that :-). wich software like paraview for example did yoy use ? thx

[@physicsgraphics954]

I didn't use any third party software. Solver of the Navier-Stokes equations was written by myself. Using the capabilities of the C++ and OpenGL (GLSL) I implemented algorithm from the article referenced in the description to the video.

[@ihato8535]

Wow. That's fantastic, actually.

[@physicsgraphics954]

Thanks!!!

[@Pulpasification]

Is this 2D ?

[@physicsgraphics954]

Yes
