Abstract

Pressure drop and heat transfer characteristics of graphene oxide nanoparticle suspensions in circular pipe flow were investigated. The concentrations of test suspensions are 0.1wt%, 0.3wt% and 0.5wt%. Friction coefficient of test suspensions in turbulent flow was reduced as compared with water. The drag reduction effect increased with increasing the concentrations of test suspensions. The maximum drag reduction was 31% at 0.5wt%. In addition, heat transfer coefficient of graphene oxide nanoparticle suspension was increased compared to water. The effect of heat-transfer enhancement increased with increasing the concentrations of test suspensions. It was found that the graphene oxide nanoparticle suspensions not only reduce the pressure drop but also increase the heat transfer in a circular pipe flow.
