Abstract
In the current study, three different approaches have been examined to enhance and to improve both the maximum speed obtained at chimney entrance and the heat transfer characteristics of the solar chimney prototype approaches have been analyzed in this work. The first approach is concerned with studying the influence of increasing number of obstacles on the maximum speed obtained, where the second approach is related to studying the influence of making throats having different area ratios at the entrance of the chimney, and the last approach deals with making round edges with diffract radii at the entrance of the chimney.
These entire schemes was numerically studied by using ANSYS FLUNT 16 by making simulated model for solar chimney in order to inspect and monitor the effect of these changes on the performance
Since the model is axisymmetric, so it was drawn as 2D axisymmetric model to minimize mesh size
The k-ԑ realizable enhanced wall function was selected for more accurate results which is totally near to the validated case.
