Overview

The purpose of this paper is to investigate the effects of Cattaneo-Christov double diffusion on a steady, viscous, magnetohydrodynamic, incompressible, electrically conducting flow of an Oldroyd-B fluid flow over a stretched sheet with mixed convection account taken into consideration along with the presence of a magnetic field, nanofluid particles, thermal diffusion and diffusion thermoeffects. In addition, the characteristics of chemical processes, the Schmidt number, thermophoresis, the Prandtl number and Brownian motion effects are taken into consideration in this research. As a result of the present use of similarity variables, the scope of application for constitutive equations that deal to mass, energy and concentration has been expanded. Making use of the bvp4c solver, which is a computational platform that runs on MATLAB ® , in order to find answers for the problem of governing equations that has been presented. In order to get an accurate measurement of the shear stress as well as the rates of heat and mass transfer at the boundary, the Sherwood number, the Nusselt number and the skin-friction coefficients are used. Tables are a useful tool for doing accurate computations using numerical values. In order to undertake a comprehensive analysis of the dynamics of the problem, we carry out an in-depth research of the concrete repercussions that are caused by a number of different aspects. After then, we use graphic approaches to accentuate and show the implications that have resulted from the situation. In addition, to get a more thorough knowledge of the memory effects, it is beneficial to do a comparative assessment of the present results and the outcomes from the past.
