摘　　要：采用标准湍流模型,O-Block结构网格划分方法,对两栖装备的推进器喷口内流场进行了数值模拟,得到了喷水推进器内部的流场特性,对比三种不同形状喷口的模拟计算结果,提出对两栖装备喷水推进系统的管道优化方案,为进一步探索提高两栖装备的喷水推进系统效率提供一定的参考。Numerical simulation of the flow fieht in nozzle of the propulsion system on amphibious equipment is made hy using turbulence model , O-Block structured meshes. The characteristics of the flow field in the nozzles are c, omputed. The optimization scheme of jet nozzle structure is proposed by comparing with the computation resuhs. Based on this, primary research has been done to provide bases for research on improving the efficiency of the propulsion system.
