Studying the Wake of a Tidal Turbine with an IBM-LBM Approach Using Realistic Inflow Conditions
Energies, 2022 The lattice Boltzmann method is used to model a horizontal axis tidal turbine. Because tidal turbines generally operate in highly turbulent flows, a synthetic eddy method is implemented to generate realistic turbulent inflow condition. The approach makes
