same smaller, rotated and with an extra fin
English: Kármán vortex street shed off a cylindrical obstruction with no-slip boundary conditions, with three ink colors for visualization. Incompressible Navier-Stokes simulation, with periodic boundary conditions, but a region of fixed downwards velocity at the top effectively nulling the vertically periodic boundary conditions.
Simulated in a simple solver I wrote. For my own documentation purposes, in case I ever want to create another video similar to this one, the internal parameters were: (tpr0.3_dt0.02_mu5e-4_vel0.2_adv1.0_N1024_radius24_no_slip_spacing16_phase1_ink5000_force300_thickness40)
