Studying the Wake of a Tidal Turbine with an IBM-LBM Approach Using Realistic Inflow Conditions

The lattice Boltzmann method is used to model a horizontal axis tidal turbine. Because turbines generally operate in highly turbulent flows, synthetic eddy implemented generate realistic inflow condition. approach makes use of the open-source code Palabos. Large simulation employed. A coupling between an immersed boundary and wall realized Calculations are performed at two different turbulence rates. upstream flow condition first set up match with experimental results. Numerical simulations turbine conditions then method. found be good agreement data. Cases three rates simulated. An almost linear evolution rate observed for axial velocity deficit. analysis propagation tip-vortices close wake carried out. It that has great impact on envelope.
