Design and Parameter Optimization of High Speed Air Compressor Impeller for Fuel Cell
A high speed air compressor for fuel cell is designed,and its aerodynamic performance is simulated by CFD method to obtain the performance curve of the air compressor,and the performance changes of the air compressor under different impeller parameters are studied,so as to realize the optimization of the impeller. Firstly,the influence of single parameter on the performance of air compressor is studied,including the number of blades,outlet width and tip clearance. Then,considering the interaction between multiple parameters,the performance change of air compressor under multiple parameters is analyzed by orthogonal experimental method.
