| Abstract: | To study the overhigh pressure in the canister during the wet-type canister missile vertical launching,the wet-type concentric canister launchers of various structure parameters are calculated numerically.The launching process of the concentric canister with 17mm space between the inside and outside and single-canister are analyzed numerically with the dynamic update method.Considering the effect of water vaporization,the flow field of vapor and liquid is resolved by Mixture model of dual-phase flow.The zon... |
