Abstract

The influences of turbulence models on the aerodynamic performance of a rotating airfoil are analyzed. An airfoil equipped with a rotating cylinder at its leading edge generates additional lift due to the Magnus effect. Numerical simulations are performed at a Reynolds number of 46,200 using six different turbulence models: standard k-epsilon, realizable k-epsilon with enhanced wall treatment(EWT), k-omega, shear stress transport, Spalart―Allmaras, and k-kl-omega. The realizable k-epsilon with EWT model shows the closest agreement with experimental data, with an error rate below 5%. This model accurately predicts the wake regions of the airfoil and the low-pressure regions around the rotating cylinder, leading to a higher lift coefficient than those predicted by other models. The present study highlights the importance of turbulence model in predicting complex flow phenomena and contributes to the foundation for future design and performance optimization of engineering applications utilizing the Magnus effect.
