| Abstract: | In a solar-heated chimney, used to promote air movement within a building, stored heat is the main source for warming air within the chimney. This creates a buoyancy pressure which draws air through the building. It is therefore important to study the effect of the orientation upon the amount of heat that can be collected by the chimney for better performance. A theoretical study was conducted using a finite difference technique which showed that the amount of heat that can be collected by a solar chimney is strongly dependent upon its azimuth. |
