Objectives: To increase the efficiency and the power output of the Energy recovery system. Methods/Statistical Analysis: A nozzle of suitable material is installed above a cooling tower of a certain height. The nozzle is used to improve the speed of the exhaust air coming out of the cooling tower exhaust. A horizontal axis wind turbine is placed over the top of the nozzle such that it is parallel to the cooling tower. The wind turbine selected is of a size slightly less than the outlet of the nozzle. Findings: A five blade wind turbine is selected as it can minimize the air wastage. The nozzle outlet diameter is slightly less than the nozzle inlet diameter so as to increase the speed at which the exhaust air flows. The turbine rotates at a much higher speed when a nozzle is attached. The performance of the wind turbine with the help of a nozzle is improved. Application/Improvements: The performance of the system is tested in the laboratory with the help of a prototype design.
