Abstract

In order to solve the poor flow uniformity inside air-to-air charge air cooler (CAC), a composite mixed-flow concept was proposed. Based on the computational fluid dynamics（CFD） and experimental methods, the performances of reference model and composite mixed-flow CAC were compared and analyzed. The results show that engine power improves by 1.54 kW with the optimized CAC instead of the reference model CAC under the same working condition.
