自从托马建立了水轮机气蚀系数δ_T与装置气蚀系数δ_y的概念以来,利用模型试验结果,由水轮机综合特性曲线确定机组的吸出高度,一直是唯一的一种方法。人们用
Since the establishment of the concept of cavitation coefficient δ_T and the cavitation coefficient δ_y of turbines, the use of model test results to determine the suction height of a turbine unit has always been the only method. People use
