520			_aIn order to reduce wind energy cost, the output power of wind turbines should be augmented. A new concept to enhance the performance of horizontal axis wind turbine is suggested in the current study by adding partial cascades at the blade tip. The effect of fitting partial cascading tip arrangement on the performance of horizontal axis wind rotors is investigated numerically using finite volume CFD ANSYS FLUENT code. The numerical study demonstrates the resulting flow pattern of this new configuration and its effect on the turbine performance. Subsequently, several design parameters are studied - over a wide range of angle of attack - to select the optimum design of the new turbine configuration. These parameters include the axial and tangential space to chord ratios and the length of the partial cascaded tip to blade tip radius. A simple two dimensional study on the cascaded airfoils is performed and the results of this study are applied to three dimensional horizontal axis wind turbines
