Oscillation of the pseudo-shock in the rectangular duct with the porous wall was investigated numerically. In the simulation, 2nd-order accurate, Harten-Yee's upwing TVD scheme was used for high resolution and numerical stability, and Chien's κ-ε two equation model was used as the turbulence model. To simulate the effect of the blowing and suction on the porous wall, Darcy's law was used on the porous wall boundary. The boundary layer thickness under the first shock wave oscillates due to the shock oscillation, which changes the strength of the first shock wave, so that it suppresses the pressure fluctuation downstream of the first shock wave. The effects of some parameters of the passive control on the pseudo-shock oscillation were investigated.
