Generalized heat and mass transport features of MHD Maxwell nanofluid flows past a linearly Bi-stretching surface in the presence of motile microorganisms and chemical reaction

Abstract

Recent studies have shown that non-Newtonian fluid flows over stretching sheets have received a lot of interest. These fluids have extensive practical applications in various fields of engineering and industries. The significance of the present study is that it is used in copper wire thinning and annealing, aerodynamic emission of plastic films, the liquid film compression process, etc. In this article, a semi-analytical simulation of the magnetohydrodynamic Maxwell nanofluid flow containing nanoparticles and microorganisms over a stretching surface has been addressed. The nanofluid flow is examined through a bi-directional linearly stretched surface. The impacts of chemical reaction, Soret, and Dufour numbers on Mawell nanofluid flow are taken into account. The aim of the existing problem is to deliberate the Cattaneo-Christov heat and mass flux model in order to examine the thermal and mass transport phenomena. In the methodology section, the computation of the higher-order ODEs are solved by means homotopy analysis method. Some interesting results are found here. The increasing Soret number and chemical reaction have reduced the temperature distribution, whereas the greater Dufour number has increased the thermal profile. In the case of the Fourier law, the temperature is greater, while in the case of the Cattaneo-Christov heat flux model, the temperature is smaller. In the case of the Fick model, the concentration is greater, while in the case of the Cattaneo-Christov mass flux model, the concentration is smaller. The greater Dufour number and reducing Soret number or the greater Soret number and reducing Dufour number have significantly declined the heat rate transport. The greater Dufour number and reducing Soret number have increased the mass transfer rate, while the greater Soret number and reducing Dufour number have reduced the mass transfer rate.
