Abstract

Fluid motions in cylindrical domains have many applications in the vital areas like as chemical processes, food industry, bioengineering, oil exploitation, etc. The aims of current research is to investigate the Darcy-Forchheimer bio-convective flow of a Second-grade nanofluid over a porous stretching cylinder. The flow model incorporates with several key factors, like magnetic fields, activation energy, non-uniform heat sources/sinks, and Joule heating effect. Additionally, the analysis is considered with the slip boundary conditions and gyrotactic microorganisms within the flow regime. The transformation of the flow model into a nonlinear system of ODEs is achieved using suitable similarity variables, and…
