摘　　要：研究了潜载导弹水下垂直发射过程中同心筒内外流场的复杂多相流动问题。采用M IXTURE多相流模型,结合考虑水汽化的气穴模型,运用有限体积法(FVM)和SIMPLE算法,求解燃气、水、蒸汽多相的N-S方程和Standardkε-湍流模型。运用动网格技术和滑移网格技术,实现了导弹出筒过程中弹体运动与多相流场的耦合求解。计算结果揭示了潜射导弹水下垂直发射过程中同心筒内外复杂多相流动的演化、流场结构和流体动力特性。The complex multiphase flow of the concentric canister launcher（CCL） of the vertical underwater launched missile was studied.By means of MIXTURE model and Cavitation model which take into account the effects of fluid compressibility,viscosity,gravity and energy transfer of gas and water,N-S equation and standard k-ε turbulence model of the multiphase mixture medium were solved by using the finite volume method（FVM）and SIMPLE arithmetic.The flow field of mixture medium and the missile motion were coupled with the assistance of dynamic meshes method and sliding meshes method.The calculation results reveal the evolution progress,flow field configuration and hydrodynamic characteristics of the complex unsteady multiphase flow in CCL during the vertical launching of an underwater missile.
