  • To analyze the transmitting process of incident shock and the transient flows,the starting process was simulated numerically.In the simulation,the control equations were the conservational Navier-Stokes equations with a species diffusion term,which describe two-dimensional viscous,compressible and unsteady flows.The cell-centered finite volume scheme was used for space discretization,and the dual-time stepping method was taken to calculate the unsteady term.The calculated results reasonably agreed with the experimental ones.The research shows that during the starting process,the velocity of incident shock changes due to the variation in inner profile,and gets its maximum at the isolator.
