Finite element analysis of hygrothermal interactions in date palm concrete, autoclaved aerated concrete, and gypsum walls using the Künzel model under arid and hot Climate

Abstract

Abstract This paper assesses the hygrothermal performance of date palm concrete (DPC), autoclaved aerated concrete (AAC), and gypsum walls for arid climates using the Künzel model and finite element method. The profiles of temperature, relative humidity, and water content were determined under different boundary conditions. Among them, DPC exhibited the highest thermal conductivity and retained more moisture; therefore, cooling occurred much faster in the case of DPC when compared with AAC and gypsum. The temperature profiles were linearly varied, humidity relative humidity profile expressed the superior hygroscopic property of DPC. These findings guide material selection for arid climates and highlight DPC for its superior thermal and moisture management.
