Aerodynamic Optimization Design of Turbocharger Compressor Impeller
摘要
Abstract
A certain type of turbocharger compressor was as the research object,using the method of reverse engineering technology of 3d scanning to construct geometric model of compressor impeller.On this basis,the profile line of the impeller was fitted parametric.And with the aim to optimize efficiency and pressure ratio,artificial neural network (ANN) and genetic algorithm were used to make aerodynamic optimization design of the impeller.The results show that the aerodynamic performance of impeller is improved greatly after optimizing,and the efficiency of optimized impeller increased by 2.01％ and pressure ratio increased by 0.12 compared to original one at the optimized point,and the integrated stability margin is also improved.关键词
