Domain decomposition for compressible Navier-Stokes equations with different discretizations and formulations. (English) Zbl 0834.76071
Summary: The purpose is to couple different numerical models and approximations for the calculation of high speed external flows governed by the compressible Navier-Stokes equations. The proposed coupling is achieved by the boundary conditions, which impose viscous fluxes and friction forces on the body for the calculation of the global external flow, and which impose Dirichlet type boundary conditions on the interface for the local model.
