SIMULAÇÃO E ANÁLISE COMPARATIVA DO FLUXO DE CALOR DE PAREDE DE TIJOLO DE BARRO COM DIFERENTES TIPOS DE ISOLAMENTOS TÉRMICO

Abstract

Among the different structures in the construction industry, clay bricks are often used to form walls and walls. Given that, in different specificities, comfort and better thermal insulation are sought, it is necessary to use insulating materials, aiming to reduce the thermal flow between the internal and external environment. The research in question carried out a comparative analysis, through simulations, using the Ansys software, of the heat flux of a clay brick wall without any type of insulating material and of the clay brick wall associated with the materials: expanded polystyrene, polystyrene extruded, cork, polyurethane foam and mortar. The results indicated that the wall without any type of insulation or coating reached the maximum heat flux of 557.87 W/m2, the sample that used the mortar propagates 0.428% more than the wall without any type of insulation. The samples of expanded polystyrene, extruded polystyrene, cork and polyurethane foam obtained, respectively, 33.27%, 26.23%, 32.68% and 17.835% of the maximum heat flux of the wall without any type of insulation or coating. However, highlighting extruded polystyrene and polyurethane foam as the best materials for thermal insulation associated with clay brick wall. Therefore, there is a direct association between the material's efficiency as a thermal insulator and its low thermal conductivity. Specific studies are proposed to optimize the use of the materials studied as thermal insulators, in different thicknesses.
