摘要
本文以水轮机导水部件流场为研究对象,提出了水轮机双列环列叶栅流场的边界元分析法。经过在计算机上编制程序计算后验证,采用该方法的计算结果与实验结果比较吻合,并且速度快,精度高。利用该方法可以对水轮机双列环列叶栅流场进行预测与筛选,流场计算结果可作为分析水流流态和评价通流部件设计方案的一个依据。
A boundary element analysis method for the flow in double circular blade cascade of hydraulic turbine aimed at the flow-ield in guide vane of hydraulic turbine is presented in this paper. By checking the results obtained from the calculation on the computer, it is proved that the results agree with those from experiment and that the calculation speed and accusacy are high. This method can be used for flow-field prediction and blade cascade sievinyg. The results of flow-field calculation can be used as a basis for analysis of flow patterns and evaluation of design scheme of flow passage elements.
