Research on Fluid Thermal Solid Coupling Analysis & Test of Intercooler
【Abstract】To achieve the coupling analysis of the flow field, temperature field, and structural field of the intercooler, Computational Fluid Dynamics (CFD) and thermal strain test methods were used to conduct coupling analysis and experiments on the flow field, temperature field, and stress field of the intercooler using a fluid thermal structure coupling method. The flow field structure, temperature, and stress distribution of the intercooler were obtained. The analysis results show that this method can effectively predict the flow field and temperature field of the intercooler.
