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...

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.

The three blades were fabricated as prototypes. Experimental studies were carried out to validate the rotational speed of each wind turbine blade in order to evaluate the performances of each blade design. Simulation results showed that the blade with the best lifting effect was the swept blade, however more vortices were created after the trailing edge and caused high induced drag to the blade itself. Results obtained showed that the elliptical blade possess the best overall performances of the three proposed designs. The fabricated prototype of the elliptical blade produced up to 508 rev/min of average rotational speed and was the highest value compared to the other two blade types.
