Analyzes of Solar Chimney Design
MetadataShow full item record
The aim of this work to study the solar chimney installed in the EPT-lab of the NTNU. The work starts with the development of a CFD model of the solar chimney and comparing with the experimental data, showing a good accuracy of the CFD results. The CFD model is used to compare three types of solar chimneys for different heights and width; obtained that the chimney installed in the EPT-lab gets higher flow rates in the most of the most of the cases. The CFD model shows a uniform temperature and velocity inside the chimney that allows developing a simple physical model of the chimney, which gives a good precision of results. Finally a simplification of the solar chimney and other systems installed in a building is simulated and also is developed another physical model for this kind of building, giving an idea of the behavior of this solar house in diverse conditions.
