Abstract

Abstract: The idea of activation energy appearing in a chemical reaction has been widely applied to the production of biodiesel, hydrogen, oil storage, geothermal manufacturing, base liquid mechanics, oil emulsified, food manufacturing, a significant renewable energy source, as well as sewage systems. This study aims to investigate the resultant repercussions of double diffusion, activation energy, Brownian motion, thermal radiation, thermophoresis, viscous dissipation, magnetic field, and Joule heating on bioconvection of a tangent hyperbolic nanofluid flow over a vertical stretching porous surface containing microbe (gyrotactic microorganisms). The fluid transport equations are converted into ordinary differential equations using appropriate self-similarity variables after being solved using the finite difference method. The impacts of key parameters on the fluid's transport properties are depicted in graphs and tables. When the dimensionless activation energy is higher, the mass transfer rate at the stretched nanomaterial sheet drops. The nanofluid concentration near the sheet minimizes by increasing the porosity parameter value, but the opposite behavior happens far from the sheet.
