Abstract
The purpose of this study is related to a numerical simulation of flows in a solar chimney. The mathematical modelling approach used is based on flows in an opened enclosure with two components: a cylinder and a disc. This analysis consists in developing a computer software with dimensionless variables, and in generalized coordinates, in order to simulate an air flow in a chimney, by taking into account different flow regimes. Thermo-hydrodynamic aspect of flows is also analysed by solving the governing equations numerically using the finite volume method with adequate boundary conditions. The results presented are related to air flow velocity and temperature distributions versus Rayleigh number and some geometrical and physical parameters, such as the height of the chimney and the solar radiation intensity. The approach undertaken in this paper is related mainly in analyzing a solar chimney power plant to produce a power of a few MW.
