摘要

摘要: 为研究武器水下发射流场特征及武器在发射过程中表面的压力变化，基于雷诺平均纳维斯托克斯方程和k-ε湍流模型，运用商用计算流体力学(CFD)软件FLUENT对武器发射过程的流场进行了数值模拟，采用2D轴对称模型，由试验测量拟合得到入口压力边界条件，运用动网格技术处理武器在发射管内的运动，在此基础上得到了发射流场特征及武器表面所受压力的变化规律，与发射试验所获的武器运动速度与位移的实测数据作对比表明，仿真结果与试验结果具有良好的一致性，因此其数值仿真结果可为武器与发射管的优化设计提供参考。

Abstract: To investigate the characteristics of water flow field and the pressure variation on weapon surface in process of weapon underwater launching, a flow field numerical simulation is performed using the commercially available computational fluid dynamics(CFD)software FLUENT based on the Reynolds averaged Navier-Stokes equations and k-ε turbulence model. Two-dimensional axisymmetric model is used in the simulation, and the inlet pressure boundary condition is set using the experimental data. Dynamic mesh method is adopted to solve the relative movement of the weapon in tube. The characteristics of launching flow field and the pressure distribution on weapon surface are thus obtained. The simulation results agree well with the moving velocity and displacement measured in launch trial. Therefore, the simulation may be regarded as an assistant tool in the optimization design of weapon and launch tube.
