Abstract

In this paper, the combined upshot of Soret and Dufoue of a convective Maxwell nanofluid on a porous perpendicular surface with nonlinear thermal emission was investigated. In the present work, the impact of permeable stretching sheet, nonlinear thermal emission, heat sour sink, Dufour and Soret effect, chemical reaction, Brownian motion and thermophoresis in a convective Maxwell nanofluid flow is widely discussed. The governing equations derived for the problem are highly nonlinear coupled partial differential equations. The governing equations were transformed into ordinary differential equations using Lie symmetry group alterations. The BVP4C MATLAB solver was employed to solve the ordinary differential equations numerically after validating the convergence of the method with existing results in the literature. The numerical results were established and discussed using tables and graphs. It was found that variations in porosity parameter (K), Dufour (Du) and Soret (Sr) improves velocity, temperature and concentration profiles respectively and the present of nonlinear thermal radiation and heat source emit more heat for the flow. Also, it is exciting to report that both porosity (K) and Dufour (Du) parameters has a strong impact on the flow of skin frictions, Nusselt number and Sherwood number. However, the current results may present applications in the areas of petroleum reservoir, heat exchangers, steel industries, cooling applications, nuclear waste disposal and so on.

1. Introduction
The attentions of several researchers on the area of combine effect of Soret and Dufour have been drowned due to the recent awakening engineering and scientific applications. It is applicable in the areas of petroleum reservoir, heat exchangers, steel industries, cooling applications, nuclear waste disposal and so on. Soret and Dufour played a vital role in the double-diffusive area. This is because their upshots orders of magnitude are smaller. The product of mass flux situated in mass equation caused by temperature slope is called Soret effect while the product of energy flux located in energy equation instigated by mass gradient is called Dufour effect. Ismail et al. established the upshots of thermo-diffusion and diffusion-thermo on a parallel porous plate. It was solved analytically and finite difference method was used to validate their results numerically. However, they noted different parallel flow behaviors due to buoyance ratio- diffusion thermo. Safae et al. dissected the upshot of heat source and thermo diffusion carried out numerically within the stretching sheet. They noted that Soret upshot is increased with the presence of R on the mean concentration and reduced with absent of R. Some analysis of Soret and Dufour effects can be seen in the studies of Bidemi and Ahmad , Michael and Isah .
The modern exploration in nanotechnology to develop the effectiveness of refined thermal systems was established as a result of novel energy sources. The size of the particles in nanofluid is nanometer which is made by suppressing the particles in a fundamental liquid. Nanofluids have been form by several forms of base fluid and nanoparticles as a means of heat transfer for diverse procedures. The most common base fluids in nanofluids are ethylene glycol, water, and motor engine oil. While water is a renewable resource, it is not ideal due to its low thermal conductivity. On the other hand, motor engine oil and ethylene glycol have high viscosity but are environmentally toxic. Additionally, mixtures of water or ethylene glycol with nanoparticles are commonly used as car coolants to enhance engine performance. Computers of high performance make used of cooling electronic technology to reach an extreme power of 100,300 W/cm2 in a microprocessor circuit. Rana et al. applied Buongiorno model to recommend a non-homogeneous type which identified seven components that influenced the upgrading of warmness modification to Nanofluid, thermophoresis and Brownian motion had been determined to be the extreme contributing components. Madhukesh et al. investigated the consequences of the states of the higher temperature variation, thermal emission and viscous heat. In addition, they improved Buongiorno mathematical model with Brownian motion, thermophoresis and gyrotactic microorganisms. Therefore, the quest for the relevant application of nanofluid drives the efforts of many authors in conducting research on the related topic in recent years which include Puneeth , Khan , Hayat , Gireesha , Hussain and Isah .
Heat and mass transfer over an extended surface is another attractive area of research with applications in many industrial and engineering activities. The prediction of heat and mass transport behaviors in non-Newtonian fluids encompasses applications in thermal engineering, metal spinning, and sphere bed processes, glass fiber, hot rolling, and so on. Zaid et al investigated the free convective flow of a viscous material concerning heat and mass transfer in a permeable channel using cubic B-spline collocation outline. Hayat et al. studied the flow of Eyring-Powell fluid of heat and mass transfer on a stretching sheet. Mahanthesh et al. addressed the heat and mass flow of chemical responses over motionless and moving pattern. Selimefendigil et al. investigated the configurations of heat and mass transfer transportation in a fluid flow through the channel pattern. Ahmed et al. analyzed the microstructural implications of the finite difference scheme to evaluate the numerical simulations of heat and mass transfer in a viscous liquid.
The nonlinear thermal radiation has attracted the attention of many researchers due to several engineering applications. Though, processing industries make use of nonlinear thermal radiation to produce heat to get a good finished product. The plants for electricity generation, rocket propulsion, turbine for gas and so on are produced from the finished products. Khan et al. inspected the significance of nonlinear Rosseland approximation in a Walter-B nanoliquid by utilizing Brownian motion, thermophoresis, and convective boundary conditions. Their results show that an increasing Schmidt number reduces the concentration of the nanofluid. Ilias et al. explored the magnetohydrodynamic heat transfer on an extending sheet. Their findings revealed how heat transfer and fluid flow impact the leading surface. Jha and Samaila supported the significance of nonlinear Rosseland approximation and thermophoresis on heat and mass transfer in mixed convective vertical channels. Increasing the radiative heat flux enhances the fluid temperature, which, in turn, causes the velocity and concentration near the porous surface to rise.
The Lie symmetry group approach has been applied by several researchers to investigate countless convective boundary problems under several flow patterns in aerodynamics, plasma physics, meteorology, fluid mechanics, chemical engineering, and various other branches of engineering. It is a scaling symmetry group used to reduce two independent variables of the model to a single variable. Several papers on Lie symmetry group approach have been published which include Ahmad et al. , Das et al. , Rashidi et al. , Kandasamy et al. and so on.
Here, our primary objective is to build upon the work of Ahmad et al. by incorporating nonlinear thermal radiation into the energy equation, considering the effects of Soret and Dufour. This will allow us to investigate the mass and energy flux, as well as the convective Maxwell nanofluid flow, on a stretching porous sheet.
2. Mathematical Analyses
The characteristics of Soret and Dufour effects in convective Maxwell nanofluid flow on a stretching porous parallel plate with nonlinear thermal radiation are examined. The nanofluid flow, driven by thermophoresis and Brownian motion, is influenced by a magnetic field . According to Figure 1, The Maxwell nanofluid is presumed to flow along the x-direction. The Boussinesq approximation is considered, and the flow is fully developed and laminar.

    AB  - In this paper, the combined upshot of Soret and Dufoue of a convective Maxwell nanofluid on a porous perpendicular surface with nonlinear thermal emission was investigated. In the present work, the impact of permeable stretching sheet, nonlinear thermal emission, heat sour sink, Dufour and Soret effect, chemical reaction, Brownian motion and thermophoresis in a convective Maxwell nanofluid flow is widely discussed. The governing equations derived for the problem are highly nonlinear coupled partial differential equations. The governing equations were transformed into ordinary differential equations using Lie symmetry group alterations. The BVP4C MATLAB solver was employed to solve the ordinary differential equations numerically after validating the convergence of the method with existing results in the literature. The numerical results were established and discussed using tables and graphs. It was found that variations in porosity parameter (K), Dufour (Du) and Soret (Sr) improves velocity, temperature and concentration profiles respectively and the present of nonlinear thermal radiation and heat source emit more heat for the flow. Also, it is exciting to report that both porosity (K) and Dufour (Du) parameters has a strong impact on the flow of skin frictions, Nusselt number and Sherwood number. However, the current results may present applications in the areas of petroleum reservoir, heat exchangers, steel industries, cooling applications, nuclear waste disposal and so on.
