The test results have proved that the flow rate widely varied and the pump efficiency is high when the pump outletline structure was altered and the outlet pressure was controlled in a special limit.
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.
