Numerical Simulation of Aerodynamics of Simple Geometries Using Approximate Calculation of Flow through the Facet of the Computational Cell Using the AUSM±up2 Method

Abstract

A three-dimensional distribution of a high-velocity gas flow around simple geometric models on an unstructured grid was calculated. The obtained results were verified. It was realized by using HySol computer code and UST3D family of computer codes, which implement the donor cell method and schemes of the AUSM family of algorithms for calculating flows through the facet of the computational cell. These codes were developed in IPMech RAS. They are based on the model of a viscous compressible heat-conducting gas, which is described by a spatial non-stationary system of Navier − Stokes equations, solved on three-dimensional un-structured tetrahedral meshes.
