Abstract

This paper presents a two dimensional numerical analysis of a horizontal circular tube to study the turbulent force convective heat transfer characteristics of hybrid nanofluid flows through the circular tube under specific heat flux of 1000 W/m2. Silver Ag and graphene HEG nanoparticles dispersed in water with volume concentration of 0.1, 0.2, 0.3, 0.5, 0.7 and 0.9 vol. % were used as working fluids for the convective heat transfer simulation. The hybrid nanofluid was studied with Reynolds number of 60,000 and 80,000 as well as inlet temperature of 293 K. Effects of nanoparticles volume concentration and Reynolds number on the Nusselt number have been presented and discussed in details. It is clear from the obtained results that the Nusselt number increases as the Reynolds number increases but decreasing trend was observed when nanoparticle volume fraction increases
