NUMERICAL INVESTIGATION OF GAS FLOWS INITIATED BY SUPERSONIC MOVEMENT OF BODIES IN ATMOSPHERE

The flow of the compressible gas is investigated by means of the developed finite-difference computer algorithms. The flow of the viscous gas is modelled on base of the completed and simplified Navier - Stokes equations. The completed equation system of the viscous shock layer for solution of which the effective iteration algorithm has been developed is used as the simplified equations. The axial-symmetric flow-around of the large length cones taking influence of the turbulence, equilibrium and unequilibrium physical-chemical processes and spatial radiation transfer into consideration has been investigated. The influence of the second approximation effects in the theory of boundary at axial-symmetric and spatial flowing-around of the large length bodies has been determined firstly. The task about body flow through the large-scale termic has been formulated firstly and solved. The method for solution of the Euler and Navier - Stokes equation on the solution dynamic-adaptive grids with application of the compact approximations has been developed.Available from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
