CFD, Nozzle, Wind power, Wind turbine.



In this paper, an effort has been made in dealing with fluid characteristic that enters a converging nozzle and analysis of the nozzle is carried out using Computational Fluid Dynamics package ANSYS WORKBENCH 14.5. The paper is the continuation of earlier work: Analytical and Experimental performance evaluation of Wind turbine with Nozzles. First, the CFD analysis will be carried out on nozzle in-front of wind turbine where streamline velocity at the exit, volume flow rate in the nozzle and pressure distribution across the nozzle will be studied. Experiments were conducted on the Wind turbine with nozzles and the corresponding power output at different air speed, and different size of nozzles were calculated. Different shapes and dimensions, with special contours and profiles of nozzles were studied. It was observed that the special contour nozzles have superior outlet velocity and low pressure at nozzle exit, the design has maximum Kinetic energy. These indicators conclude that the contraction designed with the new profile is a good enhancing of the nozzle performance.
