Electromagnetic and Darcy-Forchheimer porous model effects on hybrid nanofluid flow in conical zone of rotatable cone and expandable disc

Abstract

Primary objective of this examination is to discover hybridized nanofluid flowing and heat transport that flows between a rotatable cone positioned above an expandable disc. Hybridized nanofluid contains Cadmium telluride (CdTe) as first nanoparticle and Silicon carbide (SiC) as second nanoparticle in ethylene glycol as base fluid. Electromagnetic impact and Darcy-Forchheimer model are considered with thermal radiative fluxing. By using appropriate similarity transformation, physical phenomena may be illustrated by a collection of nondimensional equations. An in-depth analysis is conducted to examine how the expansion of the surface affects the motion and temperature layers, as well as the swirl angle from the disc surface, and heat transfers from the cone and disc walls. Results demonstrate that expanding the wall varies flowing and heat dynamics within the conical gap. Boost CdTe nanoparticles without SiC nanoparticles lower disc Nusselt numbers while increasing it in a cone. In absence of CdTe nanoparticles, SiC nanoparticles increase Nusselt numbers in disc and cone. Nusselt numbers peak for rotating cone and expanded disk at φ1=φ2=0.04. When gap angles are modest, faster wall expansion rate cools disk surface and heats cone surface. These findings have important medical and pharmacological implications in blood component separation and drilling machine cooling.
