“…Higher fidelity panel methods can model flow separation through viscous–inviscid interaction coupling. 6,7 Clearly, no single aerodynamic theory can model all aspects of the flow around and behind a wind turbine; in this work, a monolithic co-simulation framework for aeroservoelastic simulations is presented, which can make use of different aerodynamic modelling modules. BEM and panel/lattice methods are only considered, as higher fidelity CFD-based techniques are deemed to be computationally expensive for simulations at the conceptual design stage.…”

This paper describes the development of a complete methodology for the aeroservoelastic modelling of horizontal axis wind turbines at the conceptual design stage. The methodology is based on the implementation of unsteady aerodynamic modelling, advanced description of the control system and nonlinear finite element calculations in the Samcef Wind Turbines design package. The aerodynamic modelling is carried out by means of fast techniques, such as the blade element method and the unsteady vortex lattice method, including a free wake model. The complete model also includes a description of a doubly fed induction generator and its control system for variable speed operation. The Samcef Wind Turbines software features a nonlinear finite element solver with multi-body dynamics capability. The full methodology is used to perform complete aeroservoelastic simulations of a realistic 2 MW wind turbine model. The interaction between the three components of the approach is carefully analysed and presented here.

“…However, flow separation is not accounted for in any of these numerical models. Nevertheless, significant research has been carried out in an attempt to enhance the capabilities of potential flow approaches by accounting for viscous forces in 2D flows (Riziotis and Voutsinas, 2008;García, 2011;Roy and Bandyopadhyay, 2006).…”

“…In his work, Kuwahara related the strength of the nascent vortices to the Reynolds number. Roy and Badyopadhyay [14] were the first to use a panel method to represent the cylinder surface. However, the work was focused on steady state simulations, neglecting the dynamics of the vortex shedding behind the cylinder.…”
