Soret-Dufour mechanisms and thermal radiation effects on magnetized SWCNT/MWCNT nanofluid in a convective transport and solutal stratification analysis

This research elucidates the mechanisms of Soret-Dufour on magnetized SWCNT/MWCNT nanofluid in a convective transport and solutal stratification analysis. The solutal stratification plays a significant role in this study's heat and mass transfer process. The solutal stratification involves the distribution of nanoparticles within the boundary layer flow regime. The fluid flow was considered to rotate vertically downward/upward in a disk and the physical interpretation is presented as partial differential equations (PDEs). The set of PDEs was first changed into total differential equations before applying the numerical scheme of the spectral relaxation method (SRM). The magnetized SWCNT/MWCNT's numerical simulations were rigorously examined using the iterative techniques of SRM. The crucial role of pertinent flow parameters is graphically illustrated while the calculated values of engineering quantities of interest are tabulated. The azimuthal profile increases due to an increase in the magnetic parameter. An increase in the Prandtl number was found to depreciate the velocity alongside the temperature profile because of the low thermal conductivity possessed by water. A rise in thermal radiation increases the fluid thermal condition by enhancing the temperature profile. The present analysis was compared with the analysis in the literature and was found to be in good agreement.
