摘　　要：本文阐述了如何应用间隙流动的数值模拟来分析解决贯流式水轮机的一些实际问题。通过间隙流动的模拟对某电站所采用的转轮进行了数值计算和分析,并与实际运行情况进行了比较。结果表明,此项技术能够准确模拟出通道内的流动情况。随着此项技术的普遍应用以及经验的积累,将对贯流式水轮机的水力设计起到重要的指导作用。In this paper, it shows how the clearance flow numerical simulation is used to analysis and settle down the practical problem of tubular turbine. The runner hydraulic performance of a power station is calculated and analyzed. Then the results are compared to prototype operation data, which shows perfect accordance with the prototype turbine. So it will guide the hydraulic design of tubular turbine with more application and more experience.
