“…Erickson et al, [2] expanded the research scope by considering the effect of suction and injection on the flow. Further, the study regarding this topic has been extended with the presence of other physical effects including magnetic field, thermal radiation, porous effect, variable wall temperature, Ohmic heating, slip and convective boundary conditions by Damseh et al, [3], Ishak et al, [4], Jahan et al, [5], Mutlag et al, [6], Chamkha et al, [7] and recently by the works of Jamaludin and Nazar [8], Anuar et al, [9] and Shamshuddin et al, [10].…”

Adaptation from the thermal management applied in modern engine cooling system and central processing unit (CPU) in performance computer devices, present study solved the problem of steady mixed convection boundary layer flow and heat transfer on a moving vertical plate in a nanofluid with the presence of viscous dissipation and constant wall temperature. The mathematical model which is in non-linear partial differential equations is solved numerically by similarity transformation approach with the Keller-box method. The characteristics and effects of pertinent parameters considered which are Prandtl number, Lewis number, Eckert number, Brownian motion parameter, thermophoresis parameter, mixed convection parameter, concentration mixed convection parameter and plate velocity parameter are analyzed and discussed. In conclusion, there exist dual solutions in opposing flow for moving parameter range 0.18 0.48.    Further, the increase of mixed convection parameter in assisting flow results to the increase in the Nusselt number and skin friction coefficient.

“…Duwairi and Damseh et al [15] formulated and analyzed thermophoresis effects on mixed convection heat and mass transfer from vertical surfaces embedded in a saturated porous media with variable wall temperature and concentration. Damseh et al [16] obtained a nonsimilar solution to study the thermophoresis particle deposition on mixed MHD convection in porous media along a vertical surface with variable wall temperature. Mahdy and Hady [17] studied the effects of thermophoretic particle deposition on the free convective flow over a vertical flat plate embedded in a non-Newtonian fluid-saturated porous medium in the presence of a magnetic field.…”

Network simulation method (NSM) is used to solve the laminar heat and mass transfer of an electricallyconducting, heat generating/absorbing fluid past a perforated horizontal surface in the presence of viscous and Joule heating problem. The governing partial differential equations are non-dimensionalized and transformed into a system of nonlinear ordinary differential similarity equations, in a single independent variable, η. The resulting coupled, nonlinear equations are solved under appropriate transformed boundary conditions. Computations are performed for a wide range of the governing flow parameters, viz Prandtl number, thermophoretic coefficient (a function of Knudsen number), thermal conductivity parameter, wall transpiration parameter and Schmidt number. The numerical details are discussed with relevant applications. The present problem finds applications in optical fiber fabrication, aerosol filter precipitators, particle deposition on hydronautical blades, semiconductor wafer design, thermo-electronics and problems including nuclear reactor safety.

“…This method, originally developed for low speed aerodynamic boundary layers by Keller [1] has been employed in a diverse range of nonlinear magneto-hydrodynamics and coupled heat transfer problems. These include magnetic boundary layers (Chiam [2]), wavy thermal boundary layers [Rees and Pop [3]], rotating hydro-magnetic convection (Hossain et al [4]), thermal convection in porous regimes (Rees and Hossain [5]), magneto-viscoelastic heat transfer in porous media (Bég et al [6]), radiation-convection viscoelastic boundary layers (Bég et al [7]), hydro-magnetic convection from an elastic cylinder (Ishak et al [8]) and hydro-magnetic thermophoretic mixed convection in porous media (Damseh et al [9]), heat and mass transfer in micropolar regime (Bég et al [10]), radiative-convective porous media flows (Prasad et al [11]). Recently, Gorla and Vasu [12] and Gorla et al [13] have studied an unsteady convective heat transfer in a non-Newtonian nanofluid.…”

A numerical investigation of two dimensional steady magnetohydrodynamics heat and mass transfer by laminar free convection from a radiative horizontal circular cylinder in a non-Darcy porous medium is presented by taking into account the Soret/Dufour effects. The boundary layer conservation equations, which are parabolic in nature, are normalized into non-similar form and then solved numerically with the well-tested, efficient, implicit, stable Keller–Box finite-difference scheme. We use simple central difference derivatives and averages at the mid points of net rectangles to get finite difference equations with a second order truncation error. We have conducted a grid sensitivity and time calculation of the solution execution. Numerical results are obtained for the velocity, temperature and concentration distributions, as well as the local skin friction, Nusselt number and Sherwood number for several values of the parameters. The dependency of the thermophysical properties has been discussed on the parameters and shown graphically. The Darcy number accelerates the flow due to a corresponding rise in permeability of the regime and concomitant decrease in Darcian impedance. A comparative study between the previously published and present results in a limiting sense is found in an excellent agreement.
