Numerical Investigation of Irreversibility in Bioconvective Flow of Sisko Nanofluid with Arrhenius Energy

Abstract

This paper investigates modeling and analysis of entropy generation in bioconvective non-radiative Sisko nanofluid flow by stretchable cylinder. Momentum relation is modeled in view of Darcy Forchheimer and porosity effects. Dissipation, Joule heating and heat generation impacts are accounted in energy relation. Mass concertation communication is constructed in manifestation of Arrhenius energy and chemical reaction. Brownian dispersion and thermophoretic effects of solid nanoparticles in Sisko liquid are stabilized by self-propelled gyrotactic microorganisms. The flow governing model is obtained utilizing boundary layer concepts. Fluid transport equations are made dimensionless via transformations and then tackled by NDSolve code in Mathematica package. Variation in transport properties versus effective parameters is examined via graphs and tables. It is perceived from obtained results that Sisko nanofluid velocity decays versus higher curvature parameter, Hartman number, porosity and Forchheimer variable. Further, it is observed that temperature distribution enhances for heat generation variable, Eckert number, Brownian movement variable, thermophoresis motion parameter and Prandtl number. Main observations are listed in the end.
