Nanofluid Flow in Porous Media

The present chapter aims at investigating the magnetohydrodynamic (MHD) boundary layer flow and heat transfer of a non-Newtonian fluid over a stretching surface through a porous medium. Casson fluid model is utilized to describe the non-Newtonian fluid behavior. Two types of nanofluids, that is, Ag-water and Cuwater, are studied. The governing partial differential equations are transformed into a system of coupled non-linear ordinary differential equations using similarity transformations and then solved numerically using the Keller box method. Numerical results are obtained for the velocity, temperature, skin friction coefficient and Nusselt number. The influence of the various governing parameters viz. Casson parameter, magnetic parameter, porosity parameter and Prandtl number on the flow and heat transfer characteristics of the nanofluids is plotted graphically and discussed in detail. The chapter shows that with an increase in the Casson parameter, the velocity field decreases whereas the temperature profile increases. A decrease in the momentum boundary layer thickness and an increase in the thermal boundary layer thickness are noted with an increase in the magnetic parameter.

“…Buongiorno [2] in his non-homogenous equilibrium model reveals that the abnormal increase in the thermal conductivity occurs due to the presence of Brownian motion and thermophoretic diffusion of nanoparticles. A wide range of current and future applications of nano-fluids are prescribed [3][4][5][6][7][8]. Nield and Kuznetsov [9] used the Buongiorno model to study the nano-fluids with respect to free convection flow problem in the permeable medium.…”

“…Ilyas Khan et al [27] introduced a mathematical model of a convection flow of MHD nano-fluid in a channel embedded in a porous medium. The influence of the external magnetic field and thermal radiation on heat transfer intensification of nano-fluid in a porous curved enclosure is simulated by M. Sheikholeslami et al [5]. Steady 2-D MHD free convective boundary-layer flows of an electrically conducting nano-fluid over a non-linear stretching sheet, taking into account the chemical reaction and heat source/sink, was investigated by D. Makinde et al [28].…”

The present article investigates the effect of multiple slips on axisymmetric magnetohydrodynamics (MHD) buoyant nano-fluid flow over a stretching sheet with radiation and chemical effect. The non-linear partial differential equations were transformed to a non-linear control equation using an appropriate similarity transformation. The governing equations were solved through the finite element method. The influence of physical parameters such as multiple slips, magnetic, thermal radiation, Prandtl number, stretching, Brownian motion, thermophoresis, Schmidt number, Lewis number and chemical reaction on the radial velocity, temperature, solutal concentration and nano-fluid volume fraction profile were investigated. We noted that the boundary layers increases in the presence of multiple slip effects whereas, the effect of thermal slip on Nusselt number increases with the increasing values of magnetic and thermal radiation. To verify the convergence of the numerical solution, the computations were made by reducing the mesh size. Finally, our results are parallel to previous scholarly contributions.

The present research provides a numerical investigation of two dimensional nanofluid flow over an inverted cone inside a porous medium. The model is developed to incorporate non-spherical shapes of CdTe-nanoparticles in water based fluid. Simultaneous effects of pertinent parameters like volume fraction, Reynold number, Hartmann number, porosity, Grashof number, radiation parameter and Peclet number on temperature distribution and velocity profile are studied and illustrated graphically. In addition, the corresponding computational results of Nusselt number and skin frication for regulating parameters are also presented in graphs and tables. The highest Nusselt number is observed for blade-shaped CdTe particles. Furthermore, the thermal conductivity and viscosity are also calculated for non-spherical shapes of CdTe nanoparticles. The result showed that the thermal conductivity of nanofluid with blade-shaped particles is 0.94% and 1.93% greater than platelet and brick type particles. The computational results for the special case are validated by comparisons with the presented results in previous studies and the results are in perfect agreement.
