Investigation on the Effect of stack Height on Solar Chimney Power Plant Operation, Using CFD Method

Without any doubt, energy production based on renewable energies is one of the most effective methods in the near future. Solar chimney power plant is a relative novel technology for electricity production from solar energy. The solar chimney power plant is a simple power plant which is capable of converting solar energy into thermal energy in the solar collector. In the second stage, the generated thermal energy is converted into kinetic energy in the chimney and ultimately into electric energy using a combination of a wind turbine and coupled generator. In this study, a 3D-numerical method is used to evaluating of Stack height on solar chimney power plant operation and then presenting a matched relation between height and power generation. The results show that the stack height has direct influence on flow field characteristics and then on the power output of power plant.
