Numerical Solutions of the Euler Equations Simulating Vortex Flows Around Wings,

Abstract

The Euler equations have been established as an appropriate model for inviscid vortex flow. This paper demonstrates the range of this model's applicability by presentation of flowfields computed around a number of different wings with either sharp or rounded edges and at subsonic, transonic, and supersonic speeds. The emphasis here is on the physics of the flow model rather than the numerical aspects of the solution method. The results display both expected as well as unexpected vortex phenomena and they indicate the value of this computational tool. Particular attention is paid to the wake regions. (Author)
