Abstract: In this paper, a mathematical model for typical cross section of convective heating oven in automotive painting line was established with CFD software FLUENT. The two-dimension static simulation with hydrodynamic method was analyzed for the mathematical model.The advantages and disadvantages of different cross sections were compared to provide the theoretical basis for oven cross section selection. The importance of application of CFD simulation in oven design was presented. The simulation results were summarized according to the comparisons. The solutions to improve the disadvantage were discussed. The results could provide theoretical guidance for oven design.
