| Abstract: | An analysis on flow field of vehicle underhood is made by CFD method.It demonstrates that there are problems of underhood flow field such as air leakage and heat reflux.Some optimizations are made,based on the analysis including the redesign of the cooling module and an addition of a deflector.The result is that the problems are fixed and the flow of cooling system is improved. |
