Abstract
The invention relates to a method for building a turbulence model of an S-shaped feature of a low water head generator. The method comprises the following steps of: firstly, carrying out site test on the idle running parameter of the low water head generator of a water turbine of a unit, then, carrying out three-dimensional CFD (Computational Fluid Dynamics) computation on a fluid in the idle running process of the low water head generator and analyzing the mechanism for forming instability under such a working condition; and finally, comprehensively analyzing the running instability under the working condition according to site test and fluid computation and analysis results, and then, proposing a proposed project for solving the problem in a pumped storage power station. The idle running stability of the low water head of the water turbine of a pumped storage unit is researched by using a site test and CFD computation combination method, so that the method has important engineering significance and application values.
