| 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双方湍流模型，对200km/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，最终表明计算结果与试验结果基本吻合。

| Abstract: | 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. |
