带分流叶片的液力透平水力性能优化
Hydraulic performance optimization of hydraulic turbine with splitter blades
摘要
Abstract
To enhance the hydraulic performance of the turbine,an optimization method for turbine splitter blades was established based on the response surface methodology.The value ranges of five pa-rameters including circumferential position,outlet deflection angle,outlet diameter,inlet flow angle,and outlet flow angle of the splitter blade were selected through single-factor tests using numerical si-mulation.Significance analysis of each parameter was conducted using the Plackett-Burman test,and three parameters with significant effects on turbine efficiency were identified:outlet deflection angle,outlet diameter,and outlet flow angle.A regression equation between the structural parameters of the splitter blade and both efficiency and output power was established based on the response surface methodology,and the optimal combination of structural parameters for the splitter blade was obtained.The results indicate that the outlet deflection angle,outlet flow angle,and outlet diameter of the splitter blade have significant effects on turbine performance.When the outlet deflection angle is 4.8°,the outlet flow angle is 23.1°,and the outlet diameter is 80.2 mm,the comprehensive performance of the turbine is optimal.Compared with the original model under design conditions,the optimized turbine shows a 2.9%increase in efficiency and a 5.6%increase in output power.The study demonstrates that the response surface optimization method is beneficial for improving the hydraulic performance of hy-draulic turbines with splitter blades.关键词
