DSMC Simulation of Non-uniform Flow Effects behind a Conical Nozzle

Abstract

The two-dimensional cylindrical DSMC simulations around a object were conducted in order to estimate the effect of the upstream condition. Non-equilibrium between translational and rotational temperatures at the nozzle exit is approximately 10K. The shock wave generated by the object and the boundary layer developed along the nozzle wall interact around the object. The comparison between the results with the nozzle exit flow and those in the uniform flow reveals that the temperature profiles around the object are influenced by the upstream flow conditions, and that the difference is approximately 20K.
