Three-dimensional turbulent flow of the endwall region inside a centrifugal compressor impeller was studied using a Laser Doppler Velocimetry. 用三维激光多普勒测速系统测量研究了一个离心压气机转子近端壁区三维紊流流场。
The test shows the flow in the modified forebay is remarkably improved,the efficiency of the pump raised and the sludge deposit reduced. 试验研究表明,改进后的前池水流流态明显改善,水泵运行效率得到提高,并有效减少了前池的泥沙淤积。
