Numerical Simulation of Water Entry Process of Cones Considering Cavitation Pulsation
摘要
Abstract
Water entry of a vehicle,as a classical fluid mechanics problem,has long attracted extensive academic attention.However,existing research predominantly focuses on analyzing initial impact pressure peak and the trajectory during water entry,and rarely involves the fluid-structure interaction mechanisms during cavity closure stages.It is worth noting that when the vehicle is completely submerged,pressure oscillation induced by cavity closure will significantly alter the kinematic behavior of the vehicle.This mechanism has not yet been systematically studied.Current studies indicate that fluid compressibility has an important influence on simulation of the kinematic response after cavity closure.In this work,the compressible axisymmetric multiphase FVM model is used to study the water entry problem of a cone,especially the kinematic response of the cone after the cavity closure.The results show that the compressible axisymmetric multiphase FVM model can simulate this kind of water entry problem well and accurately reproduce key physical processes,such as vehicle water entry,cavity closure,jet and pressure oscillations.At the same time,the causes of vehicle acceleration oscillation are analyzed and explained.关键词
