In this paper,some preliminary calculations and the experiments were performed to figure out the flow field,inwhich some rods were normally inserted into the main flow surrounded by a porous cavity.As a result,it is foundthat the starting shock wave severely interacts with the rods,the bow shock wave,its reflections,and the porouswall,which are numerically well predicted at some conditions.Moreover,inserting the rods makes the pressureon the upper wall in the porous region increase when the main flow in the porous region is completely supersonic.The calculations also suggest that three rods cause the widest suction area.

More than inserting the rods makes the pressure on the upper wall in the porous region increase when the main flow in the porous region is completely supersonic The calculations also suggest that three rods cause the widest suction area.
