Design and development of horizontal axis wind blade in regenerative energy system for cooling tower
In Malaysia which is experiencing humid and hot climates throughout the year, usage of cooling tower is very common in most industry and company to cool down the machineries. The waste produced into the environment by these cooling towers is in the form of heat and wind energy. As an initiative for...

In Malaysia which is experiencing humid and hot climates throughout the year, usage of cooling tower is very common in most industry and company to cool down the machineries. The waste produced into the environment by these cooling towers is in the form of heat and wind energy. As an initiative for sustainable development, there is a need for development of an efficient and effective energy regenerative system. This thesis presents a work on design and development of such system, named Wasted Kinetic Energy Recovery System (WKERS) to harvest the discharged wind energy from a second source wind energy that is the cooling tower. Cooling tower provides the most suitable wind speed during operation, and the best part is that the wind supply is stable and constant. This study aims to determine the possibility of generating electricity using a regenerative system. In accordance with that, this study also aims to establish the most suitable blade design for the Horizontal Axis Wind Turbine (HAWT) of WKERS. Hence, three different types of blades, which are elliptical, swept and National Renewable Energy Laboratory (NREL) Phase VI blades were designed and their performances were evaluated for the application in WKERS. Firstly, the three blades were sketched and designed using SolidWorks software.
