Wind power is considered one of the main sources of renewable energy in the market today. In this study, different sizes and directions of channels were created inside the NACA 0012 aerofoil, and the effect of these channels were investigated on aerodynamic noise and aerodynamic performance, experimentally and numerically. The results have shown se...

... distances between the rotor and the tower can cause less sound radiation and vice versa; also, the noise is lower for upwind turbines than downwind ones [55]. Figure (19) shows the flow around a cylindrical wind turbine tower. ...
