Soret-Dufour effects on MHD heat and mass transfer of Walter's-B viscoelastic fluid over a semi-infinite vertical plate are considered. The equations of motion are set of partial differential equations; these are non-dimensionalized by introducing an appropriate non-dimensional quantity. The dimensionless equations along with the boundary conditions are solved numerically using the spectral relaxation method (SRM). All programs are coded in MATLAB R2012a. Results are presented in graphs, and numerical computations of the local skin friction, local Nusselt number and local Sherwood number are presented in a tabular form. The result revealed that as the viscoelastic parameter increases, the velocity profile close to the plate decreases but when far away from the plate, it increases slightly. The present results were found to be in good agreement with those of the existing literature.

“…Forced convective heat transfer analysis through rectangular, triangular or annular sector duct is of great importance due to its many engineering applications such as heat ex-changers, underground cables and chemical engineering processes and therefore, has been extensively researched area. [1][2][3][4][5][6][7] Furthermore, most of the fluid models existed in nature, are non-Newtonian due to their non-linear relationship between shear stress and deformation rate. [8][9][10][11] The rheological behaviour of the non-Newtonian fluid models are represented by their constitutive equations and so, have many industrial and engineering applications such as in production of many chemicals, oil, gas, rubber, syrup, juice, cleanser etc.…”

Here we numerically analyse the effects of viscous dissipation and Joule heating on forced convection heat transfer rate of electrically conducting magnetohydrodynamic, ( MHD) power law fluid flow through annular duct. Mathematical model is formulated for constant properties power law fluid with steady, incompressible and laminar fully developed flow assumptions. Heat transfer results are determined by taking constant heat flux with peripheral wall temperature “known as H1 thermal boundary condition” at the solid walls of the channel. It has been observed that the effect of viscous dissipation reduces due to enhance damping magnetic field effect by increasing the value of Hartman number, Ha, especially in the case of shear thickening fluids.

“…One of the most importance is the external magnetic field force due to its applications in aerospace technology, MHD power generator, MHD pumps and petroleum engineering etc. Therefore, several studies in existence literature 1–5 are carried out by taking an electrically conducting MHD fluid. Similarly, the combination of nano particles with base fluid gets a significant interest due to enhancement in heat transfer rate, see literature.…”

“…In this way, we get the simplified form of momentum equation in the axial direction of the flow, see literature. 3–5,9–12 In the second method, we just eliminate the deviation of velocity components with respect to axial coordinate, see Kucuk et al. 20 In this way, we get the simplified form of the momentum equation in the cross section of the channel along with the axial component in the direction of flow.…”

During this study, we have investigated the effect of magnetic field on heat transfer flow of an electrically conducting magneto-hydrodynamic, ( MHD) nano fluid through annular sector duct. The problem is formulated under the assumption of fully developed flow by ignoring the deviation of velocity components in the axial direction only; and simulated with the help of semi implicit method for pressure linked equations revised, ( SIMPLER). The effect of Hartman number, M, on fully developed forced convection flow has been determined for different values of Copper nano particles contribution in base fluid, ϕ, apex angle, β and ratio of radii, Ȓ. With increase in the value of M, a prominent effect has been observed on friction factor, fRe. Furthermore, the influence of nano particles contribution on friction factor, fRe, has been dominated, when we increase the value of M.
