摘　　要：通过仿真和试验相结合的方法,研究某客车发动机后舱门开孔位置对机舱内流场及温度场的影响。结果表明,在客车后舱门靠近风扇一侧的位置开孔,且开孔应尽量设计在发动机舱体内外压力差较大的位置,散热效果较好。Through the method of combining simulation with experiment,the authors research the influence of different hole positions opened on coach rear compartment door on the flow field and temperature field of engine compartment inside.The results show that it is better for heat dissipation effect if the holes are opened near the fan side of coach rear compartment door,and as possible opened at the position of coach rear compartment door which has larger differences between inside and outside pressures.

关 键 词：CFD 发动机舱 舱门开孔 热管理
