摘　　要：利用三维不可压缩流体的k-ε湍流运动数学模型,以计算流体力学为(CFD)理论基础,在Fluent环境下对所设计的矿车空调风道系统气流的三维流动特性模型进行进、出口风速的模拟仿真分析,并进行试验验证。试验结果表明,模型建立正确,模拟仿真分析结论可靠,对缩短矿车空调风道系统设计周期、提高产品设计可靠性具有指导意义。Using the 3D incompressible k -8 turbulence model, a typical tramcar air duct mod- el with complex structure was established based on CFD method. The wind speed at the inlet and outlet of the tramcar air conditioning duct in the 3 D model was simulated and analyzed by commercial fluid analysis Fluent software. The results show that model is correct and simulation analysis is reliable. It can make less design intervals and also proposes the guild for reliable produce design.
