摘要

摘要: 为研究超高速鱼雷(UHST)通气系统内流场的参数分布特性及其流量比例分配的实现方法，基于可压缩气-水混合物多相流模型，应用商用计算流体力学（CFD）软件FLUENT对流场进行了数值模拟。使用2D轴对称网格模型进行计算，获得了超高速鱼雷通气系统内流场的气相体积分数、压力、温度和马赫数分布云图，给出了不同位置通气流量按比例分配的通气孔尺寸设计建议。仿真结果已用于指导UHST通气系统设计，试验结果表明，设计结果良好，达到了预期目标。

Abstract: In order to investigate the characteristics of ultra high speed torpedo (UHST) ventilation system and obtain solutions of mass flow rate allocation in specified proportion, we computed the flow flied with the CFD software FLUENT based on the compressible gas-water multiphase flow model. The flow field was simulated using a 2D axisymmetric mesh, and the contours of gas volume fraction, pressure, temperature and Mach number were achieved. By analyzing the characteristics of the flow field, a scheme for designing the sizes of ventilation holes was presented to realize the allocation of mass flow rate in specified proportion. The result has been applied to design a ventilation system, and the test verified the present scheme.
