Abstract
Using a conservative numerical method, a flow of viscous heat-conducting gas in the diffusor part of a spatial axisymmetric nozzle with a slanting exit section and partially overlapped critical section is simulated. The computations are carried out in a wide variation range of the parameters affecting the behavior and structure of the flow. The effect of the critical section’s area and pressure in the confusor part on the flow parameters in the diffusor part of the nozzle, position of flow separation points, and longitudinal and cross-sectional forces acting on the internal part of the nozzle is investigated. The distributions of the flow parameters in the nozzle are reported. The computations are carried out using parallel algorithms implemented on a computer system with a cluster architecture.
