Gridfree Simulation of Turbulent Boundary Layers Using VorCat

The VorCat implementation of the 3D vortex method is described and preliminary applications to boundary layer flow and the flow past a prolate spheroid are discussed. Numerical solutions displaying the non-steady development of the turbulent vorticity field in these settings is presented. Results suggest the viability of the approach in the treatment of difficult, three-dimensional complex turbulent flows that pose significant problems for current turbulence modeling techniques.
