Abstract

In order to discuss the influence of the base cavity diameter on the flow field of the projectile, projectile with different diameter base cavity (118mm, 116mm, 114mm, 112mm, 110mm) is simulated. Flow field parameters and the aerodynamic drag coefficient of projectiles were obtained. The numerical results show that the projectile with smaller diameter base cavity has the smaller aerodynamic drag, but the difference is inapparent. The flow field of projectile with different diameter base cavity is similar, too.
