Abstract
The aim of this project is to evaluate the performance of a solar chimney tower in a typical year placed in Uruguay. Solar Updraft Tower consists of a transparent horizontal surface placed at a certain distance above the ground (collector), a tall chimney situated in the center of the collector and a turbine situated at the lower part of the tower. Stack effect, produced by the combination of a temperature difference between inner and outer air and the presence of the chimney, is used for generating air flow through the turbine and generating electric power. This work studies the thermodynamic behaviour of the system by an in-house numerical model. Verification and validation of the model is succesfully performed, and results of a case study placed in Uruguay are presented.
