A two-dimensional viscous, incompressible, unsteady flow past a bluff cylinder with sharp edges is simulated using a purely deterministic Lagrangian model incorporating viscous effects (diffusion and no-slip boundary condition). The method applied is based on a combination of the discrete vortex and the panel method. The viscous diffusion effect is simulated by means of the diffusion velocity method. The evolution of vortical flow past a square cylinder after its impulsive start and motion with constant velocity in resting liquid is simulated for moderate Reynolds numbers and several different angles of incidence.
