Exploration of Hall current effect and multiple convections in a Darcy Forchheimer flow of hybrid nanofluid over rotating permeable disk: a Stefan blowing approach

Abstract

This article explores the slip boundary layer electrically conducting hybrid-nanofluid ($\text{GO - Ti}{\text{O}}_{\text{2}}\text{/}{\text{H}}_{\text{2}}\text{O}$) flow over a rotating disk. Flow is considered to be steady and incompressible type. Hall current effect and thermal radiation are considered in flow. We carried out the analysis of heat and mass transmissions in the flow through multiple convections. The surfaces of disk subjected to the influence of Stefan blowing. By completing similarity assessment, we renovate the primary PDEs of presumed flow model into ODEs. The resulting equations are solved numerically by recalling Runge–Kutta–Fehlberg fourth–fifth order scheme through shooting system. Discussions on significance of flow features on flow specific are structured precisely via graphs and charts. The acknowledged numerical concerns are novel and distinguishing. For Forchheimer number heat transmission declines in suction and in injection both cases and rate of heat transmission is higher in injection than suction which supposes in cooling exercise, flow through rotating disk suction stands more appropriate. Process of fluid flow over rotating disk and transportation via porous forms has engineering and scientific applications like gas turbines, oil condensers, nano-bio-materials processing.
