Using a classical airfoil as example, namely the Clark-Y, the flow around this with and without ground effect was simulated with the aid of the FLUENT-UNS, finite volume CFD code. Two techniques to simulate the ground effect are used. The study also reveals the behaviour of the airfoil for small relative clearance (ratio of the ground clearance to the chord of the wing), when ground effect becomes a Venturi one.
