Abstract: On condition that CQ =1, the effects of boundary-layer suction in the bottom of convergent region of the two-dimensional convergent-divergent duct on boundary-layer development on the wall near the throat and upstream interaction region between the transonic wave and the boundary-layer are studied in more detail in this paper.The effects of boundary-layer control of the interaction region between the transonic shock-wave and boundary-layer on the bottom wall of the divergent section on the flow distortion of the downstream interaction region are also investigated.The flow dynamic distortion of the downstream interaction region with and without boundary-layer control is presented, and it is pointed out that by means of boundary-layer suction in the interaction region the peak turbulence near the bottom wall and its average value are apparently reduced.
