Investigation of dynamics of the separation of supersonic cluster munition

摘要：

　　Based on the coupling of the governing equations of fluid dynamics and rigid body motion equations of six degree of freedom (6DOF), with the use of fluent dynamic mesh technique, the separation process of cluster munition at Mach 2 is numerically simulated.The numerical results clearly show the separation process of bullets from mother bombs.The separation process can be divided into three motion states due to the different separation velocity and angular velocity of the bullet from mother bombs as the collision between bullets and mother bombs, the flying of bullets over the shock wave of mother bombs and the roll of bullets with instability.
