Abstract

On the basis of a conservative numerical method the simulations of a viscous heat conductive gas flow inside diffusor part of a spatial axisymmetrical nozzle with slanting exit section and partial overlapping of critical section are carried out. The calculations are spent in a wide range of change of the parameters that have an influence on character and structure of the flow. The researches of influence of area size of the of critical section and pressure in confusor part on flow parameters in diffusor nozzle part, position of a separation of flow, and also on the longitudinal and cross-section forces operating on an internal part of the nozzle are studied. The distributions of the parameters of a flow in thenozzle are resulted. The calculations are executed on the basis of the parallel algorithms that are realized on the computer system of cluster architecture.
