A Design for Increasing Power Using a Solar Tower Unit
Publication Date : 04/05/2019
In this work, power generation enhancement for a 2.00 meter height Hexagonal base solar chimney with a 6 double faced trapezium sides is introduced. Amount of energy acquired to rotate the generating part of the solar tower (Direct current fan on the exit) depends on the air flow which will increase with the temperature rise that is affected by the solar heat up of the double faced sides. Analysis and comparison based on taking different temperature readings in 3 cases for the stagnant fluid filling the gap of the double faced solar tower sides (air, vacuum and helium) to see the best case where the highest air temperature is reached and consequently having the highest generated power. In addition to that, a Savonius air turbine is to be fitted on the top of the tower to get more power from the unit in dark time using the wind energy which is a continuous source not relying on solar energy. Commercial power generation is not expected to be acquired from this model as it is made for the purpose of analysis that would provide useful conclusion that can be used in enhancement of the commercial model performance. Key words—Solar chimney tower, Direct current generator, Savonius turbine with Direct current generator, Temperature rise analysis, Savonius wind turbine generated power , Daily temperature variance and daily wind speed variance.
