RESUMO

This paper describes the experience gained in using a program complex "Express-3D." The program complex implies an explicit variant of kinetically consistent finite difference schemes based on the system of quasi-gasdynamical (QGD) equations. The system of QGD equations differs from the Navier-Stokes equations in specific additional dissipative terms. These terms serve as efficient numerical stabilizers. The used algorithm allows one to simulate gas flows in a wide range of Mach numbers with minimum changes in the program code. The new version of the program complex Express-3D uses multiblock nonorthogonal structured hexahedral grids. This allows one to solve complex geometry problems. Note that the computational algorithm for structured grids is usually much simpler than for widely used unstructured tetrahedral grids. The method of difference scheme construction on nonorthogonal grids is described. The program complex showed a good efficiency in solving a set of problems including those relating the subsonic and supersonic flows. Here we present the results of using the program complex for the hypersonic flow/boundary layer interaction problems. The simulation results are discussed and compared with known experimental data.
