The axisymmetric flow of an MHD Powell–Eyring fluid with viscous dissipation and Newtonian heating condition: Keller-box method P. Jayalakshmi, K. Gangadhar, M. Obulesu, P. Madhu Mohan Reddy Heat Transfer, 2023 Abstract A special investigation on the heat transfer by applying viscous dissipation and considering the Newtonian heating condition in magnetohydrodynamic Powell–Eyring fluid has been attempted. It is regarded as the flow in an axisymmetrical direction over a radially stretching surface. The converted governing system of equations is solved to obtain a closed‐form solution using the Keller‐box technique. The skin‐friction coefficient's influence fully developed local Nusselt number is then presented graphically, and temperature profiles are sorted out for the pertinent parameters. The fluid overshoot towards the plate surface with rising magnetic field strength, hence, both the fluid velocity and the hydrodynamic border line layer thickness will fall, though, the skin‐friction coefficient will increase. Various relevant results of the energy indulgence have been discussed from heating and in view of viscous dissipation phenomena. The decision with minimal cases from previous studies in the literature received confirmation of the findings.
Unsteady MHD on Convective Flow of a Newtonian Fluid Past an Inclined Plate in Presence of Chemical Reaction with Radiation Absorption and Dufour Effects Obulesu Mopuri, Raghunath Kodi. Madhu, Mohan Reddy Peram, Charankumar Ganteda, Giulio Lorenzini, Nor Azwadi Sidik Cfd Letters, 2022 In this study, emission incorporation and Dufour belongings are investigated for uneven magnetohydrodynamic assorted convection stream over a disposed holey moving shield with thermal emission, heat assimilation, and homogenous substance reactions subjected to changeable suction. The governing momentum equation, as well as the energy and mass diffusion equations, have analytical solutions. The Nusselt number, the Sherwood number, in addition to velocity, temperature, attentiveness, and skin friction, are computed and examined analytically and visually in order to observe the manipulate of a variety of parameters. Grashof number (Gr), modified Grashof number (Gm), magnetic parameter (M), permeability parameter (K), Prandtl number (Pr), Heat Sink (Q), Radiation parameter (F), Dufour parameter (Du), Radiation absorption constraint (R), Schmidt number (Sc), and Chemical reaction parameter (K0) are all non-dimensional parameters with different values. In porous medium, slow-moving chemical reaction fluids are the only source of the issue. In the future, researchers may look at the inertia effects of porous medium for high-velocity flows. Researchers interested in radiation absorption effects in porous media will find this a highly helpful resource.
