Most fluids used in industries possess a constant velocity acting with them. In spite of the fact that there have been a few studies conducted on the topic, the study of fluid flow at a constant velocity using nanofluids is still relatively unexplored. The novelty of this work is the analysis of the heat, and mass transfer of the nanofluid Al 2 O 3 -H 2 O along with a constant velocity in a rotating system with Soret-Dufour effects. This article aims to investigate the MHD nanofluid flow in a vertical plate with a porous medium taking into account viscous dissipation, Joule heating, and a non-uniform heat source/sink. The investigation is subject to steady-state incompressible flow through a vertical plate with a magnetic field and chemical reaction effects. Equations pertinent to nanofluid flow have been modeled as nonlinear partial differential equations. These equations are reformed as nondimensional ODEs utilizing suitable similarity transformations. Employing, the Runge-Kutta method the system of ODEs is solved. The physical impacts of the fluid parameters on velocity, temperature, and concentration are illustrated clearly using graphs. Tables are utilized to present the rate of heat, mass transfer as well as the skin-friction coefficient. A limiting case of our work compared with the existing literature to validate our results. Our results show that when rotation parameter rises from 4 to 6, it decreases the heat transfer rate by 10.8% and mass transfer rate by 5.9%.

This paper aims to examine the combined effects of Arrhenius activation and microorganisms on unsteady flow through a porous medium with thermophoresis and Brownian motion over an inclined stretching sheet. The governing partial differential equations are transformed into a set of non-linear ordinary differential equations using similarity analysis. The resultant non-linear coupled ordinary differential equations are solved numerically using the boundary value problem solver in MATLAB. The effects of the physical parameter such as magnetic field parameter ([Formula: see text]), thermal radiation parameter ([Formula: see text]), permeability parameter ([Formula: see text]), Eckert number ([Formula: see text]), thermophoresis parameter ([Formula: see text]) and Brownian motion parameter ([Formula: see text]) on the velocity, temperature, concentration profiles, skin friction coefficient, Nusselt number, and the local Sherwood number are presented and analysed graphically. The comparison has been made with previously published work, and there is a good agreement. These results may be helpful in geothermal engineering, energy conversation and disposal of nuclear waste material. Furthermore, scientists can employ this technique in medical fields such as gene therapy and the synthesis of drug delivery systems.

The current research article discusses the two-dimensional, laminar, steady, and incompressible third-grade viscoelastic micropolar fluid flow along with thermal radiation caused by an exponentially stretched sheet. The primary goal of this extensive study is to improve thermal transportation. Thermophoresis and Brownian motion are two key causes of nanoparticle migration in nanofluids, and their impacts on the thermophysical properties of nanofluids are significant. Micropolar fluids are investigated due to their micro-motions that are significant in convective thermal and mass transport polymer formation, nanotechnology, and electronics. The consequences of third-grade fluid parameters, thermophoresis and Brownian motion, induced magnetic field, micro-polarity, and micro-inertia density on the stream of an electrically conductive fluid are analyzed. A homogeneous magnetic field is supplied perpendicularly to the surface, and the liquid is believed to be electrically conducting. As the flow has a significant magnetic Reynolds number, the contribution of the evoked magnetic field is properly accounted in the governing equations. A mathematical model in the form of partial differential equations (PDEs) is built under certain assumptions. By invoking the suitable similarity transformation, the non-linear PDEs are modified into dimensionless coupled ordinary differential equations (ODEs). The MATLAB numerical technique bvp4c is employed to settle the subsequent ODEs together with the boundary constraints. The consequences of numerous physical parameters on the non-dimensional concentration, temperature, micropolar, velocity, and induced magnetic field profiles are portrayed in graphs. It is found that the concentration boundary layer, thermal boundary layer, and micropolar boundary layer thickness decelerate with the increment in the micro-polarity of the fluid.
