“…Bilal and Ramzan [7] presented the unsteady two-dimensional flow of mixed convection and nonlinear thermal radiation in the presence of water-based carbon nanotubes over the vertically convected stretched sheet embedded in a Darcy' Forchheimer porous media using Saffman's proposed model for the suspension of fine dust particles in the nanofluid in which strong magnetic field is applied normal to the flow. Fersadou et al [8] investigated the mixed convection heat transfer and entropy generation analysis for Cu-water nanofluid inside two interacting open cavities by heating or cooling the right and the left walls of each cavity at uniform but different heat flux densities. Khan and Zuhra [9] investigated the two dimensional magnetohydrodynamic unsteady flow and heat transfer in a thin film second grade nanofluid embedded with graphene nanoparticles past a stretching sheet.…”

The formation of three dimensional study from two dimensional study due to high intensified magnetic field is investigated for a thin film second-grade fluid with variable fluid properties. The effects of Soret, Dufour, thermophoresis, thermal radiation and viscous dissipation are taken into account in the problem. Similarity transformations are employed to convert the governing equations into dimensionless form which have been solved by using homotopy analysis method (HAM). Quite real results are achieved with the help of emerging parameters which are shown through different graphs for velocities, temperature and concentration profiles.

“…In this context, Fersadou et al [28] have recently performed a numerical study on MHD mixed convection flow and entropy generation of Cu-water nanofluid in a two interacting open rectangular cavities. They observed a nonmonotonic variation of the heat transfer rate with increasing the magnetic field strength.…”

Numerical study for the effect of an external magnetic field on the mixed convection of Al2O3–water Newtonian nanofluid in a right-angle vented trapezoidal cavity was performed using the finite volume method. The non-homogeneous Buongiorno model is applied for numerical description of the dynamic phenomena inside the cavity. The nanofluid, with low temperature and high concentration, enters the cavity through the upper open border, and is evacuated through opening placed at the right end of the bottom wall. The cavity is heated from the inclined wall, while the remainder walls are adiabatic and impermeable to both the base fluid and nanoparticles. After validation of the model, the analysis was carried out for a wide range of Hartmann number (0 ≼ Ha ≼ 100) and nanoparticles volume fraction (0 ≼ ϕ0 ≼ 0.06). The flow behavior as well as the temperature and nanoparticles distribution shows a particular sensitivity to the variations of both the Hartmann number and the nanofluid concentration. The domination of conduction mechanism at high Hartmann numbers reflects the significant effect of Brownian diffusion which tends to uniform the distribution of nanoparticles in the domain. The average Nusselt number which increases with the nanoparticles addition, depends strongly on the Hartmann number. Finally, a correlation predicting the average Nusselt number within such geometry as a function of the considered parameters is proposed.
