摘要
针对潜射航行体水下航行阶段和出水阶段,对自然超空泡和通气超空泡两种工况进行数值模拟,分析了两者的形态特性及流体动力特性。结果表明:通气超空泡可提高航行体出水过程中的速度和改善航行体的流体动力载荷,在一定程度上减小了载荷对结构的冲击。
For the vehicle in the underwater movement phase,aimed at the natural supercaviatation and ventilated supercavitation conditions,a numerical simulation will be given, from which the shape and hydrodynamics character of them will be analyzed. The re- sults imply that ventilated supercavitation can increase the speed and improve the hydrodynamics load of vehicle in the underwater movement phase, and decrease the impact of load to the structure.
