A study of an aerofoil structure used for automotive body design is being conducted and an experiment has been performed to determine the lift and drag forces produced by it by varying its Angle of Attack. The NACA0018 and NACA0015 aerofoil with a chord length of 16 cm were used for this study. Then an analysis was done with the help of (CFD) computational fluid dynamics. The results obtained by CFD analysis where compared by the experimental results which was performed on wind tunnel using NACA0018 aerofoil. The results are then presented graphically, showing pressure and velocity distributions lift and drag coefficients for the different cases which will be useful for design of automotive body structures. © 2018 SAE International.
