[4k] Aerodynamics of Different Geometries - 2d Navier Stokes Simulation
The 4k quality-setting is recommended (even for smaller screen resolutions) due to the low bitrate of the lower resolution streams.
The video shows the result of a numerical simulation of a compressible air flow around the silhouettes of four different geometries, i.e. a disk, a droplet shape, a rectangle, and the stanford bunny. The heatmap plot illustrates the speed at the current location while the streamlines and tracer particles visualize the flow direction. The time scale was slowed down by roughly a factor of three.
The simulation was done using a pseudo-spectral approach. The no-slip boundary was implemented using the method of volume penelization [1].
