Stack Effect Correlation for Rooftop Solar Chimneys

Open publisher page 5 citations

Abstract

A correlation for calculating flow rate of air in solar chimneys is developed. This correlation is based on the variables that have the most direct influence on the volume flow rate of air through a solar chimney. These variables include: the spacing between the absorbing wall and glass (chimney depth), absorbing wall temperature, inlet air temperature and height of chimney. The slope of the rooftop solar chimney, for the range of typical roofs (30°–60°) has very little influence on the flow rate. The solution of energy balance equations for various components of the solar chimney along with the newly developed correlation shows a significant improvement of the results compared to the existing stack effect correlation.
