Numerical Simulation of Vortex Flows Around Missile Configurations

摘要

This paper describes the work achieved during the recent years to improve the quality of Navier-Stokes computations for industrial purpose. The main axes for improvement are the grid adaptation strategy the turbulence modeling and the application to industrial missiles. A few years ago Navier- Stokes computations were rarely run for external aerodynamics simulations. This is no longer true. Both industrial companies (EADS Aerospatiale Matra Missiles and MATRA BAe Dynamics France) now use it on a regular basis. Nevertheless some progresses are still necessary especially for the prediction of the axial force.
