Hydraulic Design and Optimization of a LNG Hydraulic Turbine Runner

LNG hydraulic turbines used as the replacements of J–T valves play an important role in the LNG industry chain. In this study, an optimization method for hydraulic turbine impeller was established based on experimental design theory, the response surface approximation and genetic algorithm. The external characteristics are obtained by the commercial software ANSYS FLUENT. The efficient and head were chosen as objective functions, and the response surface method (RSM) and NSGA-II genetic algorithm are used to obtain the optimal combination of the parameters of the impeller. The head and hydraulic efficiency of the optimized model rise by 1.5 and 3.2%, respectively.
