采用ＣＦＤ流态分析技术，以三维紊流场的分析结果为依据，对水电站的轴流式转轮进行改型。改型结果表明：应用ＣＦＤ流态分析技术预测的水轮机性能具有很好的准确性，三维紊流场分析结果为叶片改型提供了详细的数据，提高了水轮机转轮改型设计的水平。
Based on the analysis results of three-dimensional turbulent flow field, CFD flow state analysis technology is used to retrofit axial flow runner of hydropower station. The results of the modification show that the performance of the turbine predicted by the CFD flow analysis technique is very accurate. The results of the three-dimensional turbulent flow field provide detailed data for the blade modification and improve the design of the turbine runner.
