“…The Nu declined with the growing Ha number for all studied configurations of the spinning cylinders. Nath et al [ 18 ] explored the effects of nanoparticles’ form on heat and mass transport processes in a moving lid chamber under the combined action of thermo-solutal buoyant force and magnetic field. The findings indicated that the Nusselt number is considerably dependent upon the tilted magnetic force and buoyancy ratio, however, on mass transfer the shape influence is minimal.…”

The lid-driven top wall’s influence combined with the side walls’ waviness map induce the mixed convection heat transfer, flow behavior, and entropy generation of a hybrid nanofluid (Fe3O4–MWCNT/water), a process analyzed through the present study. The working fluid occupies a permeable cubic chamber and is subjected to a magnetic field. The governing equations are solved by employing the GFEM method. The results show that the magnetic force significantly affects the working fluid’s thermal and flow behavior, where the magnetic force’s perpendicular direction remarkably improves the thermal distribution at Re = 500. Also, increasing Ha and decreasing Re drops both the irreversibility and the heat transfer rate. In addition, the highest undulation number on the wavy-sided walls gives the best heat transfer rate and the highest irreversibility.

Hydrothermal Mixed Convection in a Split-Lid-Driven Triangular Cavity Suspended by NEPCM

et al. 2023

A numerical investigation of the magnetohydrodynamics of a mixed convection of nano-enhanced phase change material (NEPCM) within a triangular chamber containing an elliptical heat source is presented in this article. The forced convection has resulted from the movement of the upper cavity, while the free convection is due to the temperature difference between the heat source and cold inclined sidewalls. Four cases are considered based on the directions of the moving of the upper wall parts, namely, Case 1, where the left part is moving in the positive direction of the X-axis and the right part moves in the opposite direction (1(+−)), Case 2, where the two parts move in the positive direction of the X-axis (2(++)), Case 3, where the two parts move in the negative direction of the X-axis (3(− −)), and Case 4, where the left part moves in the negative direction of the X-axis and the right part moves in the negative direction (4(−+)). The Galerkin finite element method (GFEM) is employed for addressing the governing equations of the system under study. The impacts of the Reynolds number (1≤Re≤100), the inclination angle of the elliptic heat source (0≤γ≤90), the nanoparticles volume fraction ϕ (0%≤ϕ≤8%) and the movement directions of the parts of the upper wall (four cases) are presented and discussed. The results suggested that increasing Re enhanced the heat transfer rate, while increasing Ha reduced it. The vertical positions of the elliptical heat source resulted in the maximum heat transmission rate. At the highest Re, changing the location of the heat source from horizontal (γ=0) to vertical (γ=90) enhanced the average Nusselt number by 60%, while choosing Case 1 for upper wall movement increased the average Nusselt number by 300% compared to Cases 2 and 3.
