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
