Basic Solar Chimney Flow Improvements
Preliminary note This paper deals with the numerical analysis procedure and results of flow simulation through solar chimney. Because of relatively low Reynolds numbers, some aerodynamic improvements could be obtained. The paper links input heat energy with geometry or air flow parameters. Basic solar chimney geometry is carried out and analyzed with CFD application in three dimensional domain....
متن کاملA Comparative Study of CFD Models of a Real Wind Turbine in Solar Chimney Power Plants
A solar chimney power plant consists of four main parts, a solar collector, a chimney, an energy storage layer, and a wind turbine. So far, several investigations on the performance of the solar chimney power plant have been conducted. Among them, different approaches have been applied to model the turbine inside the system. In particular, a real wind turbine coupled to the system was simulated...
متن کاملMeasuring Velocity Changes along a Solar Chimney
The increasing consumption of energy from fossil fuels on the one hand and the pollution created by it on the other hand has always raised the concern of replacing clean and renewable energy with fossil fuels in the human mind. Generating electricity through clean energy can be a good solution to reduce pollutants and prevent global warming. One of the most available types of renewable energy i...
متن کاملImprovement of thermal performance of a solar chimney based on a passive solar heating system with phase-change materials
Passive solar systems such as solar chimneys need solar radiation in order to work. Therefore, they cannot present stable natural ventilation when solar energy vanishes: to have a more robust and stable condition, solar energy should be stored during the day and released back during the night. Phase change materials can save additional thermal energy during the day and release it during the nig...
