“…It is noticeable that the nanoparticle parameter enhances the aggregated composite thermal conductivity. The thermal radiative flux when the medium of the flow is a porous was examined in various experimental and theoretical studies [26][27][28][29][30][31][32][33][34][35][36][37][38][39]. In these studies, wavy surfaces, semi-infinite vertical plate, stretching sheets and disks are used as boundaries of the flow domain.…”

The current simulations treat impacts of the thermal radiation on some natural convective process and entropy generation along a vertical surface impeded in a non-Darcy porous medium. Various convective practicabilities are due to various thermal boundary conditions, namely, isothermal surface with horizontal leading edge C1, uniform surface with horizontal leading edge C2, an adiabatic surface with a concentrated heat source along the horizontal leading edge C3 and a plane plume rising from a horizontal thermal source C4. Beside the boundary conditions, these convection modes are characteristic with a power index such that refers to C1, refers to C2 and refers to C3 and C4. The worked mixture is Cu-water nanofluid. The dependent variables are expanded in terms of small parameters and those are function in the permeability parameter. Numerical imitations are carried out for several of the radiation parameter concentration of the nanoparticles and the porosity of the porous medium The outcomes disclosed that, for all the considered cases, profiles of the temperature, velocity, Bejan number and entropy are enhanced as the radiation parameter is increased. In C1 (isothermal case) the zero-order of the skin friction and the Nusselt coefficient are augmented as is varied. In the same context, in C1, the growing in the radiation coefficient from 0 to 2 results in an increase in the zero-order of the skin friction by 9.4%.

“…Additional significant applications include the use of rough (wavy) walls in medical apparatus to increase the mass transfer in blood (blood oxygenator). Rough surfaces are often used as flow passages in several applications for controlling the rate of heat transfer, cooling of electronic components and the designing of ventilating-heating building [3,4]. Some of the mentioned studies include, for example, the work of Vajraelu and Sastri [1] who examined the influence of waviness of one of the walls on the flow and heat transfer characteristics of an incompressible viscous fluid confined between two long vertical walls.…”

“…Recently, the effects of chemical reaction and heat source on twodimensional free convection magneto-hydrodynamics (MHD) flow in an irregular channel with porous medium were investigated by Davika et al [3]. Most recently, two-dimensional heat transfer of a free convection MHD flow with radiation and temperature-dependent heat source of a viscous incompressible fluid in a porous medium within a wavy channel were discussed by Dada and Disu [4]. Fasogbon and Omolehin [5] examined the radiation effect on natural convection in an irregular channel.…”

The problem of coupled heat and mass transfer by free convection of a chemically reacting viscous incompressible and electrically conducting fluid confined in a vertical channel bounded by wavy wall and flat wall in the presence of diffusion-thermo (Dufour), thermal-diffusion (Soret) and internal heat source or sink is studied. The walls are maintained at constant but different temperatures and species concentrations. A uniform magnetic field β 0 is acting transversely to the walls which are assumed to be electrically non-conducting. The dimensionless governing equations are perturbed into mean part (zeroth-order) and perturbed part (first-order), using amplitude as a perturbation parameter. The first-order quantities are obtained by long wave approximation. The resulting set of coupled ordinary differential equations are solved numerically using the Adomian decomposition method. Some of the results indicating the influence of various parameters on the zeroth-order and first-order fluid flow, heat and mass transfer characteristics are presented graphically.

“…[10] analysed the heat transfer due to an unsteady stretching/shrinking cylinder with partial slip condition and suction. Heat transfer with radiation and temperature dependent heat source in MHD free convection flow in a porous medium between two vertical wavy walls has been discussed by Dada and Disu [11]. All the above investigations are free from viscoelastic fluids.…”

In this study, the unsteady magnetohydrodynamic (MHD) flow and heat trasnfer of a dusty, viscoelastic, incompressible and electrically conducting fluid in an inclined channel in the presence of thermal radiation and heat source has been investigated. The non-dimensional equations governing the flow are solved by parametric perturbation technique under the prescribed boundary conditions. The solutions of the equations governing the flow are obtained for fluid velocity, dust particle velocity, temperature and dust particle temperature profile.The results have been expressed graphically and in tabular form to observe the effects of different flow parameters. The effect of the various parameters entering in the governing equations on the flow are evaluated numerically and discussed with the help of graphs and tables.
