Cooling tower fan wings are the rotating surface with the chosen aerofoil sections. The efficiency as well as the performance of an fan mostly depends on the aerodynamic characteristics i.e. e.g. lift,drags,lifts to drag ratio ,etc of the blades besides many factors the effects of blade where are also crucial to cooling tower fan performance. This project represents the experimental investigation to explore better aerodynamic performance by increase radial velocity of fan. The aerofoil is tested in closed circuit wind tunnel. The static pressure at different angle of attack are measured from rapper and lower surface of the aerofoil through different pressure tapings by using a multi tube water manometer from the static pressure distribution, lift coefficient, drag coefficient and lift to drag ratio of aerofoil is analysed.
