Numerical Simulation of Torpedo Receiving Tube of False Sea Test Facility Based on CFD

摘要: 鱼雷接收管是假海试验设施的重要组成部分, 其主要作用是接收发射出管、沿导向管而来的鱼雷, 并使其减速、停止在接收管中。文中采用商用CFD软件, 使用剪切压力传输(SST) k-w模型并结合动网格技术, 仿真了在一系列参数条件下鱼雷进入接收管的运动过程。仿真中分别考虑了接收管的内半径、管长及雷速等参数, 得到了这些参数对鱼雷运动过程的影响。仿真结果表明, 鱼雷进入接收管由于受水体作用的影响, 具有明显的非线性特征。仿真结果可为接收管设计提供验证和支撑。Abstract: Receiving tube is an important component of false sea test facility. Its main function is to receive the launched torpedo coming along guide pipe, and to make the torpedo slow down and stop in it. In this study, the motion processes of a torpedo into the receiving tube are simulated with a series of parameters by making use of the shear stress transmission(SST) model and dynamic mesh in the commercial software CFD. The parameters include the receiving tube′s inside radii and length, the torpedo speed, etc. The effects of these parameters on the torpedo motion process are acquired. Simulations show that the process of a torpedo entering into the receiving tube has obvious nonlinear characteristics due to the effect of water. The simulation results may provide verification and support for design of receiving tube.
