Numerical and experimental study of interference flow field on separation of supersonic cluster munition

For the interference flow field on separation of supersonic dispenser,a novel method using numerical simulation and experiment is proposed in this paper.The computational solutions are well consistent with the experimental results,so the flow characteristics can be simulated satisfactorily by the method of Reynolds-averaged Navier-Stokes equations,and splitting scheme AUSM+.Analysing flow field structure specific condition,pressure characteristics is found on surface by shock disturbance,aerodynamic parameters of submunition are interfered by shock of carrier.The flow field principle is revealed.The vital reference is provided for investigating separation interference flow field of supersonic dispenser.
