Abstract:
This thesis is a part of a project searching to understand the double-skin fagade function
by intergrating of an opening used for secondary ventilation. It deals with the natural
convection into the vertical double-skin fagades. We modelled our system by a vertical
channel asymmetrically heated with uniform heat flux density. The mass conservation
equations of momentum and energy are solved using the finite volume method. Numerical
simulations are performed using Ansys Fluent CFD software. The results of the flow structure
presentation allow to observe the impact of the opening size and position on the recirculation
zone and the mass flow rate at the channel entrance. In addition, thermal results presentation
shows that the presence of the opening in the bottom of the channel increases the heat transfer
more than the other positions do.
