A finite model in a three dimensional flow field is built for automotive exhaust manifold and by using the Finite Element Analysis(FEA) the three dimensional numerical simulation is implemented on the ever turbulent flow field.
建立了排气总管三维流场的有限元模型 ,用有限元法对排气总管内的湍流流场进行了三维数值模拟、计算 ,取得了理想的结果 ,能真实地反映流场的三维特征和湍流特性。
