| Abstract |
A mathematical model of a natural ventilation system by solar chimney effect equipped with south wall was proposed in order to predict its performance under varying climates(summer and winter). Unsteady state heat transfer equations were set up using a energy balanced equation and solved using Gauss-Seidel iteration solution procedure. The ventilation performance of the solar chimney as determined from the air gap, outlet temperature, mass flow rate, ventilation rate according to the system height and instantaneous heat collection efficiency of the solar chimney are examined. As a result, this numerical study shows that system efficiency of winter mode is better than summer mode. Satisfactory correlation was obtained with experimental data. Further experimental study is required to establish complete system. |
