Actuator <strong>disc</strong>• Single <strong>wake</strong>s over flat terrains are modeled with<strong>WindSim</strong>•The tower and the nacelle of the wind turbine aremodeled by solid cells• The rotor is modeled by a <strong>porous</strong> <strong>disc</strong> providing aresistive force which is calculated from the thrustcoefficient C T• Comparisons of <strong>CFD</strong> results are presented againstexperimental data, wind tunnel tests from Vermeer et al.[1]. The numerical results are further compared againstthree analytical models for <strong>wake</strong>s [2,3,4].
