Preparation and characterization of Nanofluid (CuO – Water, TiO2 – Water)
Over the past decade, research in heat transfer enhancement using nanofluids - suspensions of nanometer-sized solid particles in a base liquid has received considerable attention all over the world. Several theoretical works to predict the effective thermo physical properties of the suspension, range from a homogeneous model to complex two phase flow model have been proposed. This work explains the preparation methods of the nanofluids (CuO-water, TiO2-water) and characterizing the nanofluid of different concentrations (0.025%, 0.05%, 0.075%, 0.1% and 0.5%). Here in this work used to calculate the density, viscosity, specific heat of nanofluids and steady state parallel plate method is used to calculate thermal conductivity of nanofluids experimentally. Results of this work show the increase in thermal conductivity, viscosity of the nanofluid by increasing the concentration and decrease of density and specific heat of nanofluid by increasing the concentration.
