| 摘 要： | 利用1／16缩比的公共汽车模型及不同倾角和长度的导流翼片，在一带有可移动地面和边界层吸收装置的开放型风洞中进行了在车辆后端面的4边上安装导流翼片时车辆后部尾流区的压强恢复及气动阻力降低的实验。对导流翼片的倾角和长度在降低大后壁车辆气动阻力中的作用及机理进行了研究。找到了能使车辆的气动阻力降低20％左右的导流翼片最佳长度及倾角。

| Abstract: | For reducing the drag of vehicles with large bluff end,a series of tests are carried out on a 1/16 -scaled bus model settled on the moving ground in an open type wind tunnel.An air deflector is closely attached to each of 4 sides of the rear end surface of the bus model with no clearance between them.The effects of length and inclined angle of air deflector on the drag of bus model are studied.Finally,optical angle and length of air deflectors are found,which can contribute about 20% drag reduction to the vehicle. |
