摘要
为了研究外置蓄能式鱼雷发射装置在发射过程中的内部流场特性,建立了该鱼雷发射装置的二维轴对称流场模型,基于一维数值仿真和流场仿真联合求解的方法数值研究了该鱼雷发射装置的内部瞬态流场,对发射装置内部流体的压力场和速度场、蓄能系统内部与发射管内部流体压力变化进行了仿真,并对仿真过程中鱼雷表面的受力情况进行了监测。分析了仿真结果,结果表明,由发射过程流场仿真获得的鱼雷内弹道结果与内弹道数学模型计算结果基本相同,所建立的发射过程流场模型基本正确。
In order to study the internal flow-field of the underwater outer storage-energy launcher,the 2D axial-symmetrical flow-field model of the launcher was built, and the internal transient flow-field of the launcher was simulated associated with the 1D numerical simulation, and the simulation results were obtained. The pressure field and the velocity field in the launcher were simulated,as well as the pressure in the storage-energy system and the tube. The force on the surface of torpedo was monitored in the simulation process, and the simulation results were analyzed. The interior ballistic results obtained by simulating the flow-field at launching process are basically the same as the results calculated from the mathematic models. The internal flow- field model of the launcher is correct.
