水轮机固定导叶与活动导叶周向相对位置的优化计算

Optimum computation of relative circumferential position of stay vanes to guide vanes of hydraulic turbine

基于无粘－边界层选代的计算模型，以水轮机导水机构的水力损失为目标函数，对固定导叶与活动导叶的周向相对位置进行了优化计算．与有关实验结果的定性比较表明本文的计算结果是合理的．

By taking the hydraulic losses of the distributor of a hydraulic turbine as the objective function, the optimum computation of the relative circumferential position of the stay vanes to guide vanes is caacced out based on the iterations between the inviscid and boundary-layer flow. The qualitative comparison with the related exPerimental results has shown that the computational results given in this paper are reasonable.
