Quasi-simultaneous interaction for prediction of aerodynamic flow over wind turbine blades
conference paper
A numerical simulation method for an accurate and fast prediction of the aerodynamic behaviour of wind turbine blades (RotorFlow) is currently under development. In this method, the total flow field around a blade is split into an inviscid external flow – to be solved with a potential flow solver – and a viscous boundary layer where integral boundary-layer equations are used. At the edge of the flow domains, both flows are coupled via an interaction formulation. The quasi-simultaneous interaction law will be used which has proven to be successful in 2D. A formulation for the 3D flow over rotating blades is now being developed.
