Simulation Code Gerris 12.06.13-2D
Analysis Type CFD
Description 2D viscous flow around a heated cylinder. A fluid is flowing at a constant velocity from the left in a channel bounded by solid walls on the top and bottom. After the initial formation of vortices, a Benard-von Kármán vortex street is formed in the wake of the cylinder.
Suggested Hardware Titanium / 1 cores
Command
mkdir images; gerris2D heated-pics.gfs >out.log
Estimated Run Time 8 minutes
