A sub-domain approach for the computation of compressible inviscid flows
Abstract
A sub-domain approach for the computation of inviscid flows is proposed within the framework of pseudo-unsteady methods. A general matching technique of two perfect fluid sub-domains is presented in the case where the systems of equations solved in each sub-domain are hyperbolic with respect to time. This technique is based on the interpretation of selected compatibility relations as transport equations. The proposed method provides a solution to the problem of fitting discontinuities (shocks and wakes). Numerical applications are presented for realistic 2D problems.
