Experimental Analysis Of Modified Roof Extractor For Wind Power Conversion In Solar Chimney Application

Solar chimney is one of the methods that is used to improve the existing natural ventilation of buildings by using the convection of air principle that occurs due to passive solar energy that transferred from the sun. The solar chimney principle and the awareness of wind power generation lead to the usage of turbine in the solar chimney to generate electricity from the wind currents that occur in the solar chimney and accordingly it is termed as a solar chimney power plant. The principles of solar chimney works by using the thermal energy that is obtained from the sun to increase the temperature of the air directly under the sunrays which causes the heated air to move upwards. This updraft is guided in a way that the wind flows into the chimney and cool air replaces the flux of heated air. Using this wind, turbine is placed in the path of the updraft and used to generate electricity.
The objective of this study is to investigate the ways to improve the output of the electricity produced by the turbine generator by manipulating the variables that are present in the solar chimney such as inlet height. This is done so that the solar chimney can be presented as a feasible alternative energy source that is more efficient than the existing alternative energy sources, which usually have a low efficiency.
