Novel energy coefficient used to predict efflux velocity of tidal current turbine [PDF]

Energy, 2018
Abstract The efflux velocity is the basis for the prediction of turbine wake. A novel energy coefficient is defined to propose a new theoretical equation to predict the efflux velocity of tidal current turbine in this paper. Several CFD cases with different tip speed ratio and solidity is conducted using the DES-SA model.
