The effects of a side wall vertical jet on sudden-expansion channel's wall pressure coefficient, surface heat transfer coefficient and main flow recirculation zone length are discussed in detail.
讨论了垂直于突扩通道主流方向的侧壁射流对壁面压力系数、传热系数及主回流区长度的影响。

The time scale is obtained through the self correlation coefficient of the sound wave. It is clear that the time scale is inverse ratio to the jet velocity under the same gas velocity.
The jet penetration height, the separation distance, the separation boundary and the pressure coefficient within the separation region are estimated, and the 3-D correction is also adopted.
