摘要： 受鱼类利用中央鳍/对鳍对流体介质产生扰动来增加运动稳定性的启发,本文在轿车尾部增加功能类似中央鳍/对鳍的扰流板,称之为方案一;针对其阻力增加,在方案一的基础上,在车后窗及汽车后备箱表面添加棱纹形态仿生功能表面,称之为方案二。利用数值模拟方法,对上述两种方案及原车模型在高速行驶状况下进行仿真分析,结果表明:方案一升力系数由原车的-0.06455降为-0.1516,后轮附着力增加,提高了轿车的操纵稳定性;方案二较好地梳理了尾部气流,延迟了气流的分离,与方案一比较,减阻率达到4.938%。

关键词: 工程仿生学, 形态仿生, 扰流板, 棱纹, 减阻

Abstract: A fish uses its central fin to interfere with fluid to improve its stability. Inspired by such phenomenon, a car spoiler with similar function is installed on the car trunk lid, which is called the first scheme. Because of drag increasing of the first scheme, a riblet bionic functional surface is mounted on the rear window and trunk lid, which is called the second scheme. Under high speed, the above two schemes and the original car model are numerically analyzed. The results show that, compared with the original car model, the aerodynamic lift coefficient of the first scheme is reduced from -0.06455 to -0.1516, which means that the adhesion of the rear wheel is increased, thus, the car's handling stability is improved. Compared with the first scheme, the drag coefficient of the second scheme is reduced by 4.938% through combed fluid flow and delayed separation of boundary layer.

Key words: bionic engineering, morphology bionic, car spoiler, riblet, drag reduction
