运用颗粒轨道模型对轴对称激波诱导矢量喷管内流场进行了数值模拟,并与纯气相条件下的计算结果进行了对比分析,研究了1～30μm不同直径颗粒的运动轨迹和内流场参数的分布特征,并对矢量喷管的推力性能进行了研究。结果表明,颗粒相的加入对射流推力矢量喷管内流场和推力性能都带来很大影响,影响规律与颗粒直径密切相关。为两相流条件下射流矢量喷管的试验研究提供了一定依据。
The particle trajectory model is used to simulate the flow field induced by an axisymmetric shock wave in a vectoring nozzle and the results are compared with the results obtained under pure gas phase conditions. The trajectories and internal flow field parameters of particles with different diameters of 1 ~ 30μm are studied. The distribution characteristics of the vector nozzle thrust performance were studied. The results show that the addition of particulate phase has a great influence on the flow field and thrust performance of the jet thrust vector nozzle. The influence law is closely related to the particle diameter. It provided a certain basis for the experimental study of jet vector nozzle under the condition of two-phase flow.
