ROTORFLOW: A quasi-simultaneous interaction method for the prediction of three-dimensional aerodynamic flow over wind turbine blades
conference paper
For the numerical prediction of the aerodynamic forces on wind turbine blades, a viscous-inviscid interaction method is applied. From a discussion on the interaction methods, focussing on their ability to simulate separated flows, it follows that the quasi-simultaneous interaction method is the most suitable. The method employed here uses only the local influence of the external flow, resulting in an algebraic expression for the interaction-law equation. The method is applied to a model problem for a three-dimensional steady, incompressible, turbulent flow over a flat plate. For attached flow the quasi-simultaneous method converges to the same solution as a flow solver using a direct interaction method.
