Abstract EN
Because roofs provide a large area to collect solar energy, they can be exploited to arrive at an architectural element that can act as a solar collector and participate in the improvement of thermal comfort.
in this axis and in order to show the importance of radiative exchanges in thermosyphon systems and the choice of roofing construction materials; a 3D numerical study is carried out on the natural convection coupled with radiative exchanges in an inclined air channel (using the commercial computational fluid dynamics software FLUENT).
Emissivity values tested correspond to those of some building materials.
From our results we affirm that the emissivity of the external roofing affects the dynamic and thermal behavior of the channels integrated under the roof.
So a good choice of material roofing is recommended in order to getting a maximum air heating by solar radiation
