摘要
Abstract
The hydraulic design of spiral cases of water turbines is conducted by means of the variable velocity moment method. On such a basis, a mathematical model is established by considering the coefficient of variable velocity moment as the design variable and the least hydraulic losses of spiral cases as the objective function. The mixed penalty function method is employed for the optimization design of a case study, and it is numerically simulated by use of CFD technology. The optimization results are compared with the traditional design ones. A conclusion is drawn that the pressure on spiral cases and flow velocity are both uniformly distributed after designed by the variable velocity moment method. The hydraulic losses are small, and the hydraulic performance is superior.关键词
