“…Convective heat transfer and the MHD visco-elastic nanofluid flow induced by a stretch film are studied by Shit et al [9]. Sheikholeslami et al [10] studied the impact of the magnetic field and thermal radiation on the hydrothermal behavior of nanofluids of Fe 3 O 4 -H 2 O . The impact of Lorentz forces on the flow of CuO-water nanofluids in a permeable housing is presented by CVFEM and Nanofluid fluxes and heat transfer in a cavity.…”

The current study investigates the impact of multiple slips on Jeffrey fluid model for unsteady magnetohydrodynamic viscoelastic buoyant nanofluid in the presence of Soret and radiation over a permeable stretching sheet. Appropriate transformations are utilized to obtain the relevant nonlinear differential system. The obtained differential system is tackled numerically with the finite element method. Effect of the controlling parameters on dimensionless quantities such as velocity, temperature, concentration, and nano-fluid volume fraction profile, as well as on dimensionless numbers such as local Nusselt, Sherwood, nano-particle Sherwood, and the local friction coefficient is analyzed. The effect of multiple slips is examined and found that the boundary layer flow increases in the presence of multiple slips. Numerically obtained solutions are contrasted with the published literature and found to be in nice agreement. The present study has many applications in coating and suspensions, cooling of metallic plate, paper production, heat exchangers technology, and materials processing exploiting.

“…Several studies have shown that heat transfer increases with φ and Reynolds number (Re) [4][5][6][7][8][9][10][11]. Also, it was reported that the Nusselt number (Nu) increases by increasing the slip velocity (u s ) on the microchannel walls [12][13][14][15]. In addition, the magnetic field can be applied to increase the heat transfer rate between the nanofluid and the microchannel walls.…”

In this study, forced convection heat transfer of water/FMWCNT nanofluid is studied inside a rectangular microchannel with triangular ribs on the lower wall numerically. The nanofluid flow is affected by a uniform magnetic field. The ribs have an insulating wall and a wall at a constant temperature. The other walls of the microchannel are insulated. Slip boundary condition is imposed on the walls and the temperature jump is ignored. The effect of different parameters such as Reynolds number, Hartmann number, slip coefficient and volume fraction of nanoparticles on the velocity and temperature distributions are investigated. The results are presented as the velocity and temperature profiles and local and average Nusselt numbers. The results demonstrate that the heat transfer rate and Nusselt number increase with the Reynolds number and the intensity of the magnetic field. Also, an enhancement in the volume fraction of nanoparticles and the slip coefficient leads to an increase in the heat transfer rate.

“…The unsteady two phase magnetohydrodynamic nanofluid over porous stretched wedge with inclusion of tangent non-Newtonian fluid is considered by Mahdy and Chamkha [24]. Later on, the authors [25][26][27][28][29][30][31][32] analyzed the heat transfer characteristics of various flow configurations such as plate, shrinking surface and squeezing plates in a suspension of nanoparticles like copper, titanium, silver nanoparticle and combination of fluids (Fe 2 O 3 , Al 2 O 3 and graphene) and highlighted that the nanoparticles improves the conducting nature of the flow. A few investigators have deliberated the impact of magnetic field on the heat and mass transport enactment owing to its importance in a number of technological, industrialized and the energy generation viewpoint.…”

Natural nonlinear convection of dusty fluid in a suspension of multi-wall carbon nanotubes nanoparticles with different temperature of water and suction

This study addresses the nonlinear free convective flow of a conducting dusty nanofluid (multi wall carbon nanotubes + water + micrometer sized dust particles) over a stretched cylinder at different temperatures (10 °C and 50 °C) in the presence of Cattaneo-Christov heat flux, heat source. The mainly arising equations of motion such as continuity, momentum and energy are simplified with the suitable dimensionless variables and solved numerically using the Runge-Kutta method. A numerical simulation is executed with inclusion of multi-wall carbon nanoparticles and dust particles into different temperatures (10 °C and 50 °C) of base fluid water. Calculations for the wall friction coefficient and Nusselt number are carried out and demonstrated in tables. To authenticate the attained results we have offered the comparison with the already published results. A few graphical pictures are plotted to scrutinize the physical insight of the numerically modeled problem for the several flow parameters and found that the multi-walled carbon nanotubes + water at 10 °C dusty nanofluid shows better heat and mass transfer rate compared to temperature at 50 °C. Due to nonlinear convection the friction factor is reduced in the presence of the magnetic field. The Biot number encourages the wall friction, heat and mass transfer rates of both cases.
