摘要

An optimized design method of a reverse pump turbine is provided. A method of optimizing a reverse rotation type pump turbine according to an exemplary embodiment of the present invention includes a first impeller including a first impeller and a second impeller disposed apart from the first impeller by a predetermined distance, A method of optimizing design of a reverse rotation type pump turbine including an impeller, comprising the steps of: selecting design variables affecting response and response parameters of a reverse rotation type pump turbine considering the shapes of the first and second wings; The step of generating the orthogonal array table, the step of deriving the value of the response variable through the numerical analysis in the orthogonal array table, and the step of calculating the value of the design variable having the optimum reaction variable value in the response variable value.
