摘要
在分析泵喷射推进器的基础上,建立了其数值仿真的物理模型和数学模型,确定了求解的边界条件,利用CFD软件FLUENT对泵喷射推进器的内流场进行了数值仿真.获得了泵喷射推进器转子叶片和定子叶片上的速度分布及其表面压力分布,并由此计算了泵喷射推进器的效率和所产生的推力,为泵喷射推进器的设计及其优化打下了基础.
On the basis of analyzing pumpjet propulsor, inside flow fields are numerically simulated by using the software FLUENT, on the condition of setting up the physical models and the mathematic models and determining the boundary conditions. The velocity distributions and the surface pressure distributions of rotor blades and statot blades are acquired, furthermore, the efficiency and the thrust of the pump -jet propulsor are calculated, to lay foundation for the design and the optimization of pumpjet propulsors.
