Extract

The Euler equations are proving to be an appropriate model for in viscid 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 at 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.
