Performance assessment of solar chimney power plants with natural thermal energy storage materials on ground: CFD analysis with experimental validation

This study interprets the effect of using sand or gravel as energy storage unit in solar chimney power plants. The effect of using low-cost materials is evaluated. Based on the Manzanares pilot plant, a 3D CFD model is created. Geometric parameters are kept constant in simulations performed with ANS...
