Short summary
The paper provides improved models for flow curvature effects associated with airfoils rotating about an axis, such as the blades of vertical-axis turbines. The models are implemented into an efficient simulation framework using an advanced actuator line method for enforcing both the aerodynamic forces and the aerodynamic moment, and they are validated against reference results. This research was conducted to obtain efficient and accurate simulations of curved unsteady flows, such as in wind energy.
