Abstract:

An integral equation method is presented for solution of the Navier Stokes equations for stalling aerofoil, cascade or bluff body flows. Vorticity created at the aerofoil or body surface at each time step of a numerical procedure, is diffused into the mainstream and convected by the local velocity vector. Viscous diffusion is simulated by a model skin to Brownian motion whereby all shed vorticity elements are given random displacements at each time step. Solutions are shown for boundary layers, bluff bodies, aerofoils and a first attempt at a cascade. Author
