Analytical all-induction state model for wind turbine wakes

Abstract

Analytical wind turbine wake models are prone to failure when the turbine induction factor increases, as they do not account for the increasingly important effects of low wake pressure. This work proposes a novel analytical wake model which incorporates the effect of wake pressure in its predictions. Comparison with high-fidelity wind turbine simulations shows that the newly developed model is comparable to conventional ones at low induction factors, but continues to be accurate at higher induction factors where existing models break down.
