Abstract:

Direct numerical simulation of complex gas dynamics problems computational experiment is performed with the help of Euler, Navier-Stokes and Boltzmann equations. The basic principles of the computational experiment are formulated and the results for various gas dynamics problems of a complex internal structure are presented. The problems examined include the transonic regime super-critical flows including transition through sound velocity, flows with a jet injected into the main stream and diffraction problems. Body wake flows are studied at various Reynolds numbers. The structure of a shock wave provides an example of rarefied gas flows at various Mach numbers. A set of control tests is worked out for the estimation of calculation accuracy. Author
