Abstract

A numerical simulation of the flow field around a projectile overtaking a preceding shock wave is carried out by solving the three-dimensional thin-layer Navier-Stokes equations. A domain decomposition method with the FSA (fortified solution algorithm) interface scheme is used to supply reasonable grid configurations for such unsteady flow filed. Computed results show that the complicated interaction flow fields are observed during the overtaking. The results of the two- and three-dimensional flow field computations are compared, and the characteristic features of the three-dimensional flow field are shown. Time histories of the aerodynamic forces show that the projectile suffers strong asymmetric forces during the overtaking which may make the trajectory of the projectile unstable.
