Karman vortex street at Re = 80
Calculation of the Kármán vortex street for the two-dimensional flow around an infinite cylinder, with Re = 80.
The calculation uses a stream function-vorticity formulation and a second order finite difference method in log-polar coordinates. The spatial resolution is 401x402 grid points. The vorticity equation is integrated in time using the MATLAB function ode23.m.
Massless particles one grid point away from the cylinder are continuously released into the steady-state periodic flow field: 380 particles are released every time step.
