摘要
为了探寻一种适用于降落伞减速的灵巧子弹伞弹系统的气动特性数值仿真方法,本文针对某子弹及伞采用有限体积法求解不可压流的N-S方程,K-ERNG湍流模型,对其外流场特性进行了数值仿真分析计算,仿真结果与理论分析及试验结果基本一致,表明该方法对具有伞弹系统的子弹外流场的数值仿真是有效可行的,可以近似模拟风洞试验.
In order to find a suitable analysis method for the aerodynamic properties of parachute-bomb system, the external flow field of the terminal guidance submunition decelerated by the parachute system is simulated in this paper. The finite volume method and K-ERNG turbulent model are used to solve the incompressible N-S equations. The calculated results for flow field show good agreement with the academic and experimental results. It is proved that the simulation method is valid and available to carry on the smart submunition aerodynamic design.
