High resolution vortex simulation of bluff body flows

A. Leonard and P. Koumoutsakos, Journal of Wind Engineering and Industrial Aerodynamics, 46-7,315-325, 1993


New advances in vortex methods for the simulation of unsteady incompressible flows, the fast-vortex algorithm for convection and the method of particle-strength exchange for viscous diffusion, are discussed. The application to bluff body flows is demonstrated for transient flows past a circular cylinder for Re = 40 to 9500.
