In the computation, the inlet of the primary flow uses the mass flowrate boundary condition. The inlet of the second flow and the outlet of the mixing flow use the pressure boundary condition.
在计算过程中，主流进口采用质量流量边界条件，二次流进口和混合流出口采用压力边界条件，均设置为环境大气压力。
Therefore, the good or bad condition of flow in the sump directly exerts an influence on the flow field of the pump inlet and consequently leads to poor pump system performance.
进水池中流态的好坏直接影响泵进口的流场，从而影响到水泵的系统性能。
