摘　　要：潜射导弹出筒过程的研究对其水弹道以及水下动载荷的计算具有重要的意义。本文采用多相流模型和动网格技术,求解非定常雷诺平均NS方程,对考虑潜艇平动影响的导弹冷弹射出筒过程进行了三维非定常数值模拟。三维数值模拟体现出筒口效应、发射气团现象等经典实验现象与实验符合较好,说明本文方法能够有效地揭示导弹出筒过程中多相流体间的相互作用以及相应的流体动力特性,通过分析这些现象中导弹所受冲击的形成机理,为工程应用提供有意义的参考。The research on vertical launching of missile from submarine is very significant for predicting its underwater trajectory and dynamic load.In this paper,the unsteady RANS equations are solved with multiphase model and dynamic gridding.The results achieved by using the three dimensional numerical simulation of the cold launching from a moving submarine agree in main aspects with the phenomenon appearing in the experiments.It shows that the method presented can reveal the interactions between the fluids of multiphase and the related hydrodynamic responses,which may contribute to engineering applications.
