摘要：

A deterministic Vortex sheet method is derived for application to boundary layer flows. Diffusive vorticity exchange is through adaptation of a scheme proposed by Fishelov (J. Comput. Phys. 86, 211, 1990) to Vortex elements with a sheet-like structure. Special measures are taken to maintain the integrity of the Vortex sheet representation at inflow and solid boundaries. The flow domain is periodically regridded to ensure that it is well covered by Vortex elements. in calculations of a startup channel flow and zero-pressure gradient and stagnation boundary layers, smooth instantaneous realizations of the velocity field are achieved which closely match exact results.
