摘要
运用流体动力学数值计算软件 CFX,采用三维粘性不可压缩雷诺平均应力方程和 k- ε双方程湍流模型 ,对 2 0 0 km/h电动旅客列车进行了表面压力、速度分布及空气阻力的计算分析。所得结果与相应实车试验和风洞模型试验结果进行了比较分析 。
Calculations and analyses are made on surface pressure, velocity distribution as well as aerodynamic resistance, using Computational Fluids Dynamics software CFX, 3D viscous incompressible Reynolds averaged Navier stokes equations and turbulence model k ε double equation. The results are compared with those of field test and wind tunnel model test. Comparison shows good agreement.
