Abstract:Ten fire pumps with different designs were simulated by SIMPLEC method and standard model.The static pressure,turbulent kinetic energy, streamlines distributions and external performance were analyzed and compared. The results showed as follows.(1) Blade angle of outlet is very sensitive to the pump head and hump;the head increases quickly after appending blades or splitting blades;(2) Splitter blades with good inner flow and turbulent kinetic energy distribution could improve the perfor-mance of pump,such as efficiency,head and so on;(3)The influence on the performance of low specific speed fire pump acted by throat area is sensitive;it has benefit to expand the range of the high efficiency and increase the maximum efficiency by increasing pump throat area
