摘要

提出了由水冲压发动机推进的超空泡航行器简易结构。基于Reynolds平均N-S方程、Mixture多相流模型和完全空化模型,建立了超空泡航行器內外流场仿真模型。基于模型,对不同航速和结构参数下航行器流场进行仿真。分析得到航速、进水管路入口直径和喉径对航行器减阻及摄水性能影响规律,进一步计算得到以一定初速发射的超空泡航行器射程和速度变化规律。

Abstract

A simple configuration for a supercavitation vehicle propelled by water ramjet was proposed. Based on Reynolds averaged N-S equations, mixture multiphase model, and full cavitation model, the numerical simulation method for the internal and external flow field of the supercavitation vehicle was established. Based on this model, the flow field of a supercavitation vehicle with different configure parameters and sailing speed were simulated. Through analyzing the simulation results, the relation function between sailing speed, inlet diameter of water pipe, throat diameter of water pipe and the vehicle performance of drag reduction and water ingestion were obtained. Furthermore, the range and velocity variation law were calculated for a supercavitation vehicle launched at certain muzzle velocity. The conclusions have some instructional significance in the development of supercavitation vehicles.

Key words： supercavitation vehicle; water ramjet; water pipe; internal and external flow field; Mixture; numerical simulation
