  • To solve effect problem of spacecraft lifetime caused by on-orbit spacecraft plume effect, numerical simulation and experimental validation were used. Based on the experiment studies of DFH series satellite attitude control thruster nozzle plume, axial-symmetric nozzle model was established. Rectangle calculation region was chosen, and a certain boundary condition and calculation condition were assumed. The calculations were carried out by axial-symmetric single gas direct simulation Monte Carlo (DSMC) method for plume of corresponding experiment state. By comparing numerical simulation results with experimental results, the calculation results of plume agree well with the experiment flow characteristics. It shows that the program of axial-symmetric single gas DSMC method designed is accurate and effective.
