摘　　要：建立了装甲车辆冷却风道空气湍流流动与传热的计算流体力学(CFD)计算模型,提出了确定动力舱外计算区域和网格生成步骤及保证网格质量的实用方法,应用商业软件Fluent进行3维数值求解。检验了CFD计算结果精度。将CFD计算模型应用于车辆冷却风道设计中,对风扇导流板空气阻力进行了计算,取得了较好的效果。A CFD calculation model for the computation of airflow and heat transfer in an armored vehicle cooling wind tunnel is established. A utility method on determining computation region outside power train compartment and on producing mesh step that ensure adequate grid mass is put forward. A 3-D numerical value is solved by using commercial software Fluent. Precision of the CFD calculated results is verified. By applying the CFD to design of the vehicle cooling wind tunnel, air flow resistance of fan lead stream board is calculated, and the good effect of the CFD method in design of wind tunnel is achieved.
