摘要：
Numerical simulation method was adopted to investigate the effects of the fin structures and parameters on the thermal hydraulic performance in a charged air cooler (CAC). Three dimension k-ε turbulence model, block-structured grid and fluid-solid coupling method combined with shell conduction model were adopted and DOE (Orthogonal experimental design) method was used to simulate the fluid flow and heat transfer performances of 18 virtual geometry units. The range and variance analyses were carried out, and wind tunnel tests were used to validate the effectiveness of the method. The investigation indicates the effects of fin structure and pitch on heat transfer performance are most notable, and those of the fin height and fin wavy amplitude follows, as for fluid flow resistance, the effect of fin height is most obvious, and those of the wavy amplitude and pitch are second to it. The effect of wavy length on performance can be ignored. The simulation findings validated by wind tunnel tests are consistent with engineering experiences.
