Abstract

In this study, the convective phenomena are considered to be the features of microorganisms in an Eyring-Powell nanoliquid induced by a stretching cylinder. The study considered chemical reaction and thermal radiation to be novel factors due to the saturation of the flow by the Darcy-Forchheimer porous space. By selecting appropriate similarity transformations, the model equations that regulate the fluid flow have been transformed into non-linear ordinary differential equations. The MATLAB software is then used to solve the non-dimensionalized differential equations via the finite difference-based bvp-4c utility. The graphical representation of the numerical solutions illustrates the role of the physical variables elaborated on the volume fraction, velocity, microorganism density, and temperature of the nanoparticles. Furthermore, a physical explanation is used for the rates of microorganism density, heat transfer, mass transfer, and drag friction. The current inquiry demonstrates that the fluid variable results in intensification in velocity and a diminution in temperature of the Eyring-Powell fluid, whereas the curvature constraint results in a rise in velocity. The decrease in the heat transfer rate can be attributed to the thermophoretic, Brownian movement, and thermal radiation. Regulating drag friction at the wall is achieved by manipulating the Darcy number values.
