Navier-Stokes numerical simulations of a model scale in-line HAWTs farm

Nowadays, research on renewable energy is strongly increasing because of both the increased pollution and the decreased availability of fossil fuel.Since the end of the Second World War, the conversion of kinetic energy of the wind into other energy forms has emerged as one of the most cost-effective production system among the non-polluting techniques. In fact,wind turbines evolved from rather primitive windmills to technologically advanced mechanical systems: the state-of-the-art horizontal axes wind turbines (HAWT) have rotor diameters of more than 150m and more than 7MW installed power. Consequently, Wind Turbine Farms (WTF) have been deployed with an exponential acceleration during the last decades: currently, WTFs contribution to the overall energy production has be came remarkable.
