| 摘 要： | 针对在轨航天器羽流效应对航天器整体寿命的影响,在"DFH"系列卫星姿控发动机喷管羽流实验研究的基础上,建立喷管的轴对称模型,选取矩形计算区域,设定一定的边界条件和计算条件,采用轴对称单组分直接模拟蒙特卡罗(DSMC,Direct Simulation Monte Carlo)方法对相应实验状态的羽流流场进行数值模拟研究.通过对比数值模拟结果和实验测量结果,表明DSMC数值模拟羽流流场的计算结果符合实际流动规律,实验验证了所编制的轴对称DSMC数值模拟程序的正确性和有效性.

| Abstract: | 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 ... |
