摘要 应用计算流体力学软件FLUENT,对固体火箭发动机喷管内的二维两相粘性湍流进行数值模拟。用拉格朗日方法对粒子的速度、温度、轨迹进行处理。5组级别粒子尺寸的气流被用来实验和计算,计算结果表明,粒子尺寸分布对两相流场有显著影响。 A fully coupled two-phase viscid nozzle flow of SRM is numerically simulated with FLUENT software. The velocity, temperature and trajectory of the particles are treated with Lagrangian approach. The gas that contains the combination of five classes of particles was tested and calculated. The results indicate particle distribution influences flow field significantly.
