Research on Heat Exchanger between Water with Air in an Intercooler Based on CFD

摘要

The purpose of this paper is to present the numerical simulation on heat exchanger between the hot air with cold water in an intercooler using perpendicular flow plate fins. In this paper, the structural characteristics of plate fin in the intercooler were analyzed and the finite volume model in computational fluid dynamics fluent software was established. The structured grid is used to mesh. The finite volume model is imported to Fluent before simulation. The distributions of inlet-outlet temperature and pressures of intake air and coolant in two channels of intercooler are shown in the result. The heat transfer rate from air to water was achieved for this intercooler heat exchanger. In addition, the simulation result provides a scientific basis for structure and performance optimization to intercooler on the engine.
