Dufour and Soret Influence on MHD of an Oldroyd-B Fluid over a Stretching Sheet with Nanoparticles

Abstract

In this study, the heat and mass transfer characteristics of a two-dimensional incompressible Oldroyd-B fluid over a stretching sheet in the presence of Soret, Dufour, and nanoparticles are investigated. The effects of elasticity and magnetohydrodynamics on flow are being studied. The transport equations contain Brownian motion and thermophoresis. The governing partial differential equations and associated boundary conditions are dimension less using sufficient similarity variables. The resulting ordinary differential equations are solved using the successive linearization method. It has been quantitatively measured and explored how different embedded thermophysical characteristics affect fluid velocity, temperature, concentration, Nusselt number, and Sherwood number. The temperature and concentration distribution increase when the values of Du and Sr rise. As Nb estimations rise, Nusselt number estimates fall. It should be emphasized that the influence is shown to be quite modest as a retardation time is increased. A comparison of one instance of our findings with those previously published in the literature reveals a very strong agreement.
