Aspects of the Application of a Euler-Equation Method to the Simulation of Leading-Edge Vortex Flow

摘要

The flow about a 65-deg sharp-edged cropped delta wing is simulated by solving the Euler equations. Solutions are obtained for transonic vortex flow with and without shocks including cases with strong vortices. The paper concentrates on the assessment of the capability of the Euler method to simulate the details of the flow field, especially with respect to the influence of artificial dissipation and the influence of the computational mesh.
