Wind energy has become a very important branch of renewable energy for electricity production. Wind farms are necessary for large wind power plants. To make wind power economically feasible, it is important to maximize the efficiency of converting wind energy into mechanical energy for turbines located downstream of each other’s. Subsequently, the wind turbines distribution in a wind farm is a very important parameter in wind energy projects [1]. The wakes behind wind turbines have significant effects on the downstream flow, which is characterized by low wind speed and more intensive turbulence than that of the free stream flow [2]. To improve the performance of the wind farm, it is necessary to adjust the most effective separation distance between turbines. However, the experimental work on such a problem is very expensive and highly complex. Alternatively, the Computational Fluid Dynamics (CFD) offers a …
