The use of solar air collectors for room ventilation: a study using two numerical approaches.

Author(s) : MORET RODRIGUES A., CANHA DA PIEDADE A., AWBI H. B.

Summary

Solar energy air-collectors installed on the sun-oriented building facades can be used for improving natural ventilation of adjacent rooms. The basis of the physical process is an unbalanced buoyancy force arising from the temperature difference between ambient and the air inside the room. In the paper, two numerical approaches of different complexity are applied to study the airflow produced by a solar-air collector in a room, a simplified model based on the integral equations of motion and Bernoulli theorem, and a more complex computational fluid dynamics model called Vortex.
