Role of hybrid nanoparticles in thermal performance of peristaltic flow of Eyring–Powell fluid model

Abstract

Nanoparticles have great potential to improve thermophysical properties and thermal execution. At different polymer fixations, hybridization of Eyring–Powell nanofluid model with peristaltic flow is done due to its high accuracy and consistency as found in the measurements of fluid time frame. The transport equations of the problem have been incorporated under the assumptions of long wave length and lubrication approximations. The conditions of wavelength include the impacts of thermophoretic dissemination of nanoparticles with Brownian movement. The coupled nonlinear boundary value problem has been analytically solved employing the homotopic approach. Key consideration includes material constant, thermophoresis parameter, Brownian movement parameter, Eyring–Powell parameter, local temperature Grashof number and local nanoparticles Grashof number. Key findings of the analysis reveal that fluid axial velocity enhances with larger aspect ratio and thermophoresis parameter but decays for Brownian motion and fluid factors. On the other hand, the channel aspect ratio exhibits inverse relation with peristaltic pressure, fluid temperature and nanoparticles concentration.
