The goal of the current study is to theoretically evaluate the heat and mass transfer behavior of magnetohydrodynamic Casson and Williamson fluids as they pass through a stretched sheet with Brownian and thermophoresis effects. The evolution of high-density heat devices necessitates efficient thermal transportation. For these requirements, the concept of nanofluid plays an active role. This article describes the effects of Cattaneo–Christov. This study introduces new concepts such as motile microorganism bioconvection, non-Fourier heat flux, and activation energy. A Runge–Kutta-based shooting procedure is used to solve the problem. The effects of the relevant parameters on velocity, thermal, concentration, and motile microorganisms are depicted graphically. The computed reduced Nusselt, Sherwood, and motile density numbers are displayed in tables in this study. When compared to the Williamson fluid, the thermal and concentration fields of the Casson fluid are heavily influenced by the parameters.

The main goal of the research is to investigate the effects of temperature and concentration slip on the MHD Casson-Williamson nanofluid flow through a porous sheet, with a focus on viscous dissipation. This research has a novel approach, as it seeks to incorporate various factors that have not been previously studied in this context. Moreover, an inclined magnetic field from the outside is applied to the stretched surface. Besides this, it is considered that the viscosity of nanofluids depends on temperature while all other physical characteristics are taken to be constant. It is hypothesized that the expanding surface that stretched exponentially is what caused the flow motions of the nanofluid. There are several engineering applications for this type of study, which is based on MHD non-Newtonian nanofluid flow across a stretched surface with heat generation and viscous dissipation. They include solar energy storage, energy distribution, chemical reactors, and the manufacturing of polymers. To examine the heat transmission and mass transfer rates, tools like thermophoresis and Brownian motion were implemented. The flow problem is formally represented as a set of nonlinear PDEs that are then, through the use of dimensionless variables, converted into a set of ODEs. To numerically obtain the solution to the problem, the shifted Chebyshev polynomials of the third-kind approximation along with the spectral collocation technique are utilized. This process transforms the existing model into an algebraic equation system that was created as a restricted optimization problem, which is then optimized to obtain the solution and the unknown coefficients. For a variety of pertinent parameter values, the graphic and tabular representations of the concentration, temperature, velocities, rate of heat mass transfer, and shear stresses of nano-fluids at the surface of the sheet are shown. Finally, there is a remarkable amount of agreement between the earlier investigation and the comparison research that was conducted. The results indicate that an increase in the magnetic parameter, Casson parameter, viscosity parameter, and suction parameter causes a reduction in both the velocity and boundary layer thickness. In addition, as the viscosity parameter, Casson parameter, and magnetic parameter increase, both the concentration and temperature exhibit an increase in their values.

“…Later on, Alali and Megahed [11] went on to look at the slip velocity phenomenon and the impacts of thermal radiation on the heat transfer mechanism for the Casson nanofluid's liquid-film flow. Recently, Yousef et al [12] assessed the effects of chemical reactions on a porous-medium dissipative Casson-Williamson nanofluid model. Likewise, the Williamson nanofluid flow model under the influence of the gyrotactic microorganisms was studied by Areshi et al [13].…”

Thisresearch investigated the flow and heat mass transmission of a thermal Buongiornonanofluid film caused by an unsteady stretched sheet. The movement of the nanoparticles throughthe thin film layer is caused by the strength of the heat flow and the stretching force of the sheetworking together. The thermal thin-film flow and heat mechanism, and the properties of mass transferalong the film layer, were comprehensively investigated. The consequences of the heat generation,magnetic field, and dissipation phenomenon were also thoroughly examined. Using appropriatedimensionless variables, the fundamental time-dependent equations of thin film nanofluid flowand heat mass transfer were modeled and converted to the ordinary differential equations system.Mathematica version 12 is the software that was used to build the numerical code here. Next, theshooting technique was applied to numerically solve the transformed equations. The elegance ofthe shooting technique and evidence of the consistency, dependability, and precision of our acquiredresults is that the results are more effective than those for the thin film nanofluid equations that arenow available. There is a significant degree of consistency between the recently calculated resultsand the results that have been published for a limiting condition. Investigations were conducted intothe effects of a variety of parameters on the flow of nanoliquid films, including the Nusselt number,skin friction, and Sherwood number. In addition, a detailed overview of the physical embeddedparameters is provided through graphs and tables. However, the important features of the mostrelevant outcomes are the effects of higher porous and unsteadiness parameters on minimizing thethickness of the thin film; and the viscoelastic parameter has the reverse effect. Additionally, it is seenthat the temperature profile improves as a result of higher thermophoresis and Brownian motionparameter values.
