摘要：Because of the head and efficiency of the circulating water pump in a power plant could not satisfy application requirement, the guide vane and impeller were optimized according to the CFD method. The optimization of the mixed-flow pump effectively improves the flow state at the design and high discharge conditions. Finally, the CFD results show that the head is improved by 3.49m and the efficiency is improved by 3.16% after the optimization, which has met the use requirements.
