In this study, the mechanism of wake deflection induced by Coriolis force is firstly investigated through a momentum balance analysis. A new wake deflection model is then proposed to analytically predict the wake center trajectory at the hub height. The proposed wake deflection model is subsequently incorporated in a Gaussian based wake model. The velocity deficits in the wake predicted by the proposed model show good agreement with the numerical results obtained by high fidelity wind turbine wake simulation.
