AB - This paper’s main objective is to perform a numerical analysis of the heat and mass transfer that occurs during the mixed convective drying of porous walls containing hybrid nanofluid. The porous wall, used to dry the brick, is positioned in a vertical channel and has three different phases: a solid phase, a hybrid nanofluid phase, and a gas phase. In order to accomplish this, we created a 2-D code using COMSOL Multiphysics to resolve the equations relating mass, momentum, species, and energy. The impact of various parameters, including ambient temperature, initial hybrid nanofluid saturation, and nanoparticle volume percent, on heat and mass transmission was examined after this numerical code’s validity. As the volume percentage of nanoparticles rises, it is discovered that the temperature of the porous medium is significantly lowered. The heat and mass transfer of the water-Al2O3-MgO hybrid nanofluid has been discovered to be much less than that of pure water and the water-Al2O3-SiO2. As the ambient temperature rises, it takes less time for the second phase to dry.
