Aggregation of nanoparticles in flow of Carreau fluid containing gyrotactic microorganisms on extendable cylinder with viscous dissipation aspects by performing numerical simulations

Abstract

Owing to the excellent utilizations of nanotechnology in industrial processes, thermal engineering, cooling processes, solar systems, and so forth, current contribution is articulated. This investigation aims to explore the physical characterization of Carreau nanofluid over a linearly extendable cylinder along with the appliance of bioconvection phenomenon. Self-propagated movement of gyrotactic microorganisms sustained by buoyancy forces along with additional thermal aspects of viscous dissipation are engrossed in the study. The leading governing system is mutated into as set of (nonlinear) ordinary differential equations by means of adequate similar alterations. The attended resultant problem is contested with fourth-order Runge-Kutta integration and shooting schemes. A detailed graphical framework is constituted in a comparative manner for cylindrical and flat surfaces to examine the thermo-physical attributes of involved physical parameters on associated profiles. The impact of identical parameters on the skin friction factor and rate of transfers by quantitative and graphical display is also presented.
