Four computational models of propellers are applied to the Workshop for Integrated Propeller Prediction (WIPP) dataset at Mach 0.08 conditions with a propeller thrust coefficient of 0.40 using the NASA Langley FUN3D solver: a uniform actuator disk, a radially distributed actuator disk, a second radially distributed actuator disk that includes swirl effects, and discrete moving overset blades. Results clearly indicate that swirl effects are essential for the accurate prediction of wing aerodynamic properties in the vicinity of the propeller, especially at low angles of attack. At higher angles of attack, the effects of swirl were observed to diminish.
