Wake Patterns Computed by a Vortex Method

Abstract

A wake is modelled by a vortex sheet carrying positive and negative circulation. The sheet's evolution is computed by the vortex-blob method. Initial conditions and circulation density for the vortex sheet are chosen to simulate some of the wake patterns observed in the soap-film experiments of Couder et.al.(2,3).
