Abstract

Abstract: In industry, double-diffusive convection has various and important technical applications. These applications include electronic apparatus cooling, drying processes, fuel cells, geothermal engineering, and thermal storage. We provide an entropy-thermal based analysis of magnetized Boussinesq-free double-diffusive convection engendered by internal heat and concentration source block in a nanofluid-filled C-shaped inclined confined space. Findings may be interpreted and assessed in terms of the leading variables such as Lewis number (Le = 2 to 8), Hartmann number (Ha= 0 to 20), buoyancy ratio (N = 1 to 3), and Rayleigh number (Ra = 10 5 and 10 6 ). Besides, to determine the effective geometry and good control of the phenomenon, the investigation also covered the system geometry parameters including the position of the concentration and heat source block (h/L = 0.2 to 0.8) and the inclination angle of the enclosure (δ = 0°–90°). We state that the mass and heat transfer rates increase with Ra, N, and δ while decreasing with Ha, Le, and h/L parameters. Furthermore, when Le, Ha, N, and δ increase, overall entropy increases, whereas it decreases as the h/L parameter increases.
