Optimized Computation of Linetype Parameters of Swirl Supercharger Used in Vehicles

Linetype parameters of swirl are significant to performance of swirl supercharger.First,on the basis of analysis of relations among linetype parameters,factors effecting on mechanical load and volume efficiency are fully analyzed and an object function is established;then,all linetype parameters' influence on technics and shape dimension of swirl supercharger have been sufficiently taken into consideration until restricted conditions are obtained;finally,linetype parameters are optimized using the compound method.This also makes a good preparation for design of swirl supercharger in the future.
