Résumé

This paper presents a numerical study on heat transfer by laminar natural convection within multilayer domes with uniform spacing heated from the outside. The flow and temperature fields within the domed enclosure were obtained using the control volume approach combined with the fully implicit scheme. The results showed that the convection heat transfer for fully hemispheric domes (half of spheres) may reach more than 13% higher than that for low profile domes (hemispherical caps) for small gap spacings. The critical gap spacing that yields the maximum heat transfer was quantified for each dome shape.
