Abstract

Abstract The present research paper investigates the performance of divergent solar chimney power plant. A numerical model has been developed to predict the performance of divergent solar chimney power plant using ANSYS 15.0. Mesh refinement is performed in conventional solar chimney power plant and divergent solar chimney power plant. The numerical model has been validated with experimental data of Manzanares pilot plant. The simulated results are in good agreement with the experimental results. The k-ε (Realizable) turbulent model has been used for final simulation after thorough numerical testing. The collector efficiency and power output have been obtained in case of divergent solar chimney power plant deployed with divergence and exhaust fan at chimney outlet. The collector efficiency and power production capacity rose by 6.7% and 15% by 2 ° of divergence. Deployment of the chimney exhaust pump led to further 11.74% rise in net power output.
