Numerical Simulation of Collaborative Optimization for Bulb Tubular Turbine Based on Orthogonal Experiment
摘要
Abstract
A collaborative optimization method based on orthogonal experimental design and CFD numerical simulation is used to study the changes in tailpipe pressure and vorticity before and after optimization of a bulb tubular turbine.Taking the bulb tubular turbine of the Burqin Power Station in Xinjiang as the research object,a 3-factor 4-level orthogonal experimental scheme was constructed for blade angle,guide vane opening,and operating head.The sensitivity patterns of each factor on unit efficiency and tailpipe recovery coefficient were explored through range analysis method.Combined with three-dimensional numerical simulation analysis of the entire flow channel,the evolution process of the tailpipe flow field before and after coordinated optimization was analyzed.The results showed that:The blade angle had a dominant effect on efficiency(range 30.59),while the guide vane opening had a significant effect on the recovery coefficient of the tailwater pipe(range 0.074).The recovery coefficient of the tailwater pipe of the bulb turbine under the optimal combination(A4B4C1)reached 0.858,an increase of 11.9%compared to before optimization.After optimization,the peak vorticity of the tailpipe decreased,and the uniformity of flow velocity at each section was improved.This can provide reference for collaborative optimization research of bulb tubular turbines.关键词
