| Abstract: | This paper applied non-smooth surface to automobile,and used CFD to research the feasibility of aerodynamic drag reduction on automobile by using bionic non-smooth automobile surface.Furthermore,an orthogonal experiment was designed.By calculating the aerodynamic drag coefficient of automobile,the performances of aerodynamic drag reduction on different bionic non-smooth automobile surface were compared,and the most reasonable bionic non-smooth automobile surface structure was obtained,that is able to reduce aerodynamic drag. |
