Because of the confinement of objective condition, the spiral case and draft tube measurement of prototype is smaller than that scaling from the model, so in design stage, analysis of the effects on turbine performance after modifying is necessary.

受客观条件制约，电站真机蜗壳和尾水管尺寸比按模型换算的真机尺寸值要小一些，在设计阶段需要通过数值模拟分析尺寸改小后对机组水力性能的影响。

It is not enough to resolve all of the problems related to the hydraulic stability only to analyze the stable field in passing components. Finally, the paper numerically simulated the transient field in prototype's draft tube under different operating conditions by means of Reynolds stress turbulence model and analyzed the law of motion of vortex rope as well as the performance of low-frequency pressure pulsation and compared with field test results.
