The dynamics of rotor wakes and the behaviour of tip vortices have emerged as critical areas of investigation in rotorcraft aerodynamics. These phenomena underpin not only the performance and ...

Once computed, the results of the simulation show where the air behind the blades is most disturbed. As each blade rotates, a vortex is shed from its tip. In forward flight, when the blade is ...

This paper describes the formulation of a new model for the wake of a horizontal-axis wind turbine. As in many other models, the trailing vorticity is represented by a number of vortex lines which ...
