Performance Assessment of an Al2O3-Water Nanofluid in Terms of Thermophsyical Properties

Abstract

In this work, an analysis is carried out for the thermophysical properties including thermal conductivity, and viscosity of aluminum oxide-water nanofluid for different particle volume concentration and temperature. The analysis is carried out using previously developed correlations of viscosity and thermal conductivity. A strong dependence of thermophysical properties with particle volume fraction and temperature is reported. The key thermo-physical property i.e. thermal conductivity of nanoparticle-water blend shows a linear behavior with the increase in particle volume fraction. Furthermore, the other thermo-physical property i.e. viscosity of nanoparticle-water blend shows a linear increasing behavior with the increment in the particle vnlume fraction.
