摘要：

Pseudoshock in straight channel flows was numerically simulated by solving the two-dimensional time-averaged Navier-Stokes equations. The objectives of the present simulation were to investigate the influence of parameters on the structure of pseudoshocks and to validate the model of the pseudoshock mechanism proposed in the previous paper. In this simulation, Harten-Yee's second-order-accuracy TVD scheme was used for high resolution of the shock wave and numerical stability, and Baldwin-Lomax's algebraic model was used for turbulent flows. The computational results agreed well with the experimental ones and with the proposed model of lambda- and X-type pseudoshocks.
