Radiation-Absorption and Dufour Effects on Magnetohydrodynamic Rotating Flow of a Nanofluid Over a Semi-Infinite Vertical Moving Plate with a Constant Heat Source

Abstract

The united consequences of diffusion thermo as well as radiation absorption on magnetohydrodynamic (MHD) complimentary convection revolving flows of nanofluids over a semi unlimited porous stirring plate by the invariable temperature resource are investigated. Utilizing the perturbations methodology, the velocity distributions,temperatures as well as the concentrations distributions are obtained and examined through their graphical representation. Besides that, the skin friction coefficient, Nusselt number as well as the Sherwood number are obtained analytically and are also arithmetically discussed with reference to the leading parameters. It is observed that the diffusion thermo parameter or the radiation absorption parameter augments the velocity in addition to the fluid temperatures throughout the fluid region. This enhancement is most significant for silver nanoparticles. This is owing to the higher conductance of the solid particles of Ag than that of TiO2. It is also observed that the concentration frontier layer thickness reduces by an increase in the chemically-reacting parameter. This is because the chemically molecular diffusivity decreases for higher quantities of Kr. Also,the Nusselt number reduces while the Sherwood number enhances by increasing the value of the suction parameter.
