Design and Fabrication of a Turbine having NACA 2415 Blades and Feasibility Study of its Application in Cooling Tower

In modern world, energy is a blessing, but its production is a problem with many human and economic ramifications. Comparing with others, solar and wind energies are much popular but have their own problems, primarily cost. Some of experiments are at MIT's Media Laboratory are happening with cheap alternative energy sources. Wind energy is more efficient according to research, than solar energy. Mathematically it is proven, with the help of a 3 square meter turbine where velocity of wind is 36 km per hour and with 30% of total efficiency about 300 watt can be obtained. The main contents of this project and thesis include the design, construction and calculating the performance of aerofoil shaped turbine blade. To construct the aero foil shaped turbine three blades and a wood-hub are used. A shaft is fitted with hub with 5 cm diameter; a metallic gear is there for supporting the other end. In addition, gearing system is there to make the speed of output shaft are more high. A24 volt generator is also connected to the output shaft. The primary output was 6 watt & can apply this output power in various purposes like to run energy saving lamp, to charge mobile battery & other charge storage battery. A model has been used for simulation since the site of the actual turbine was not feasible for collecting effective data. The model was tested at different wind speeds and rpm of the rotor with respect to the amount of electricity produced.
