Implementation of a Vortex Method for the Prediction of Separated Incompressible Flows. G.U. Aero Report 9425

A vortex method has been developed to predict separated, incompressible flows around closed bodies. The method does not require any empirical data to model separation and employs random walks to simulate flow diffusion. The introduction of a control zone around the body results in realistic predictions for problems exhibiting different separation characteristics. Results of some cases are presented, including both a stationary and moving aerofoil in unsteady flow. The level of agreement between the results from the numerical model and tests is encouraging
