A special treatment is made in outlet boundary in which the subsonic and supersonic flow exist commonly. Block-Line-Gauss-Siedel method is used to solve THD differencing equations.
对离散方程采用线超松驰方法迭代求解，在亚音速与超音速气流共同存在的出口边界分情况进行了处理。

The inlet port is connected to the pressure line in and the outlet port should be connected back into the non-pressurized reservoir.
进气口连接线的压力和出口港口应连接到非加压水库回来。
