The present work employs a computational model for predicting the detailed internal flow inside a solar chimney plant, for various turbine characteristics. The model features governing partial differential equations expressing mass, momentum and energy conservation, as well as the transport equations for the kinetic energy of turbulence and its rate of dissipation. The equations are all expressed in an axi-symmetric boundary-fitted co-ordinate system. The turbine characteristics are embedded implicitly within the model. The paper focuses on predicting the effect of turbine characteristics on the flow field within the solar plant as well as its effect on overall plant performance. It reveals strong dependence of plant performance on the selected turbine characteristics.
