Flow and heat transfer mechanism of engine-oil based hybrid nanofluid due to a nonlinearly extending surface: A comparative study

Abstract

ABSTRACT The present report emphasizes on the thermo-physical feature of the radiative hydrodynamic stream of hybrid nanofluid above a nonlinearly extending surface with uneven heat sink or source effects. The equations yielded by mathematical modeling are accessed numerically by employing bvp5c MATLAB package. The uniqueness of the current scrutiny is to deliberate the simultaneous results of the radiative hydrodynamic flow along extending surface for nanofluid (ethylene glycol + CuO) and hybrid nanofluid (ethylene glycol + CuO + Al2O3) instances. Furthermore, the influences of sundry physical parameters on the flow and thermic gradients are graphed, and wall friction and heat transmission rate are illustrated via tables for nanofluid and hybrid nanofluid situations. The outcomes reveal that the energy transport rate in a hybrid nanofluid case is substantially larger than the nanofluid case. Moreover, the viscous dissipation parameter performs a major role in enriching the temperature gradient of the hybrid nanoliquid than the nanoliquid. The prime application of the present work can be found in industrial processing, where control over heat transport is required.
