Numerical Study of Viscoelastic Behaviour of Nanofluids

Abstract

The addition of nanoparticles to the fluids such as water has improved load carrying capacity of such fluids. The key idea is to exploit the viscoelastic properties of nanofluids which can withstand higher loads by adding nanoscale particles in low volumetric fractions to a fluid in order to improve their rheological, mechanical, and thermal properties. The behaviour of shear stress and the viscosity of nanofluids have been studied based on some of the empirical models developed. In this paper an overview of the recent developments in the study of heat transfer using nanofluids is presented. The nonmaterial in base fluid shows some agglomeration in 5μm -8μm, however and the load carrying capacity of the fluid are found to be improved due to the addition of nanoparticles in the base fluid. The viscoelastic properties of the nanofluids are found to be improved with increasing concentration.
