Computation of Viscous-Inviscid Interactions (Le Calcul de l'Interaction Fluide Parfait-Fluide Visqueux)

摘要

The Symposium surveys the status of current research in computational aerodynamics based on methods solving a viscous-inviscid interaction problem. In spite of limitation in the models or numerical techniques for shock wave boundary layer interaction or trailing edge problems, the situation is well advanced in unseparated, steady two-dimensional flow, with the potential approximation for the inviscid part. Progress has advanced in the computational of separations, based on strong interaction models. It would be fruitful to make use of the complete Euler equations in transonic flow. Progress toward strong interaction methods is much less advanced in unsteady or three-dimensional flow, but seems likely. The development of strong interaction methods, highly connected with that of 'Inviscid' and 'Navier-Stokes' numerical techniques, appears as mandatory to having access to practical application needs.
