摘要
Abstract
The numerical simulation is based on the Reynolds -Averaged-Navier-Stokes ( RANS) equations.The Finite-Volume Method is used in the discretization of the control equations , and Volume of Fluid Method is adopted for the multiphase flows of water -entry cavity .The dynamic mesh method is used to control the constant speed of the cylinder .The effects of with or without cylinder afterbody and various length afterbody on the vertical water-entry cavity was numerically investigated .The calculation results of the cavity shape of water entry of the sphere were directly compared with the “ideal cavity” of A· May, which showed that the computation methodology properly captures the key features of constant speed vertical water entry cavity .The results of various length afterbodies showed that the cavity af-ter cone with afterbody had different dynamics feature different and different spatial distribu-ting of phase .关键词
