Entropy generation analysis of hybrid nanofluid in a microchannel with slip flow, convective boundary and nonlinear heat flux

Abstract

Purpose

Thermal features of hybrid nanoliquid consist of Cu–Ti, CuO–TiO₂ and C71500–Ti₆Al₄V/H₂O as hybrid mixtures of nano-sized particles in a base fluid through a microchannel are inspected. In this study, flow model of Darcy–Forchheimer is hired to examine the flow of hybrid composition.

Design/methodology/approach

The equations which delineate the physical occurrence of the flow are resolved via Runge–Kutta–Fehlberg scheme united through shooting procedure.

Findings

It is established that flow velocity of hybrid nano composition satisfies the identity U_(_{CuO-TiO2/water})>U_(_{Cu–Ti/water})>U_(_{C71500–Ti6Al4V/water}).

Originality/value

Hybrid nanofluid flow of Cu–Ti, CuO–TiO₂ and C71500–Ti₆Al₄V/H₂O hybrid mixtures in a base fluid through a microchannel are inspected.
