摘　　要：通过对灯泡贯流式机组四叶片和两叶片的CFD分析及模型试验研究,提出两叶片转轮适用于超低水头条件发电,可弥补原有四叶片灯泡贯流式机组在超低水头条件下的缺陷,提高汛期发电量和机组运行稳定性。Through the CFD analysis and model test research on the four-blade and two-blade tubular generators,it is found that the two-blade runner is suitable for power generation under ultra-low water head,because it can offset the shortcomings of the original four-blade bulb tubular units under ultra-low water head and improve the power generation in the flood season and the operation stability of the unit.
