Abstract
Keywords: automotive deportante wing, ground effect, Coanda effect, aerodynamic characteristics.
The aim of this study is to investigate the effect of ground proximity on the aerodynamic lift and drag of a deportante wing assisted by Coanda effect. Using a classical airfoil as example, namely the Clark-Y, the flow around this with both ground effect and Coanda effect was simulated with the aid of the ANSYS CFX, finite volume CFD code. The results show that Coanda effect can be used to reduce trailing edge separation, in order to optimize the aerodynamic characteristics of the wings. Practically applications are concerning the automotive aerodynamic devices as ailerons, used to generate downforce in order to increase the stability and handling of the vehicles.
