Effect of the turbulence model on the simulation of the air flow in a solar chimney

The present paper focus on the impact of the numerical model on the air flow characteristics inside a solar chimney power plant. Computational simulations have been carried out using the commercial computational fluid dynamics (CFD) code Ansys-Fluent 17.0. Five turbulence models were tested to present the distribution of the air flow characteristics such as the magnitude velocity, the temperature, the pressure and the turbulence characteristics. The above work showed that the turbulence model types affect directly the numerical results. Computational results were based on the experimental results founded in the literature to choose the adequate model.
