This paper presents a new method for the numerical calculation of the movement of free shear layers in two-dimensional and quasi-three-dimensional flow. This method greatly reduces the numerical error which is associated with principal value integrals. New sets of equivalent vortices are created at each time step in the computation, giving rather better simulation of the behavior of vortex sheets. The authors review the most important earlier papers and recalculate some of their results. Solutions for vortex sheet development for several other problems of interest are also presented.
