| 摘 要： | 为提高潜艇推进效率,降低潜艇阻力和噪声,提出了一种潜艇内王推进系统及其结构布局,初步建立了内置推进系统的理论分析方法和设计思路.对推进系统的管道进行了参数化设计,并借助计算流体力学软件,用体积力代替螺旋桨产生的力场,对不同管道参数下的潜艇周围及管道内部的流场进行了数值模拟,结果表明:增大管道的进口面积可以减小管道阻力,...

| Abstract: | To increase the efficiency of propulsor and decrease the noise level of submarine,a kind of internal submarine propulsor and its configuration were presented.And methods for theoretical analysis and design of this internal propulsor were proposed primarily.Besides,the tube of the propulsor was parametrically designed.Using CFD software,the flow field around the submarine with different tube parameters was simulated by adopting volume force as a substitute for propeller force.The calculated results indicate ... |
