CHARACTERIZATION OF ETHYLENE GLYCOL BASED TiO 2 NANOFLUID PREPARED BY PULSED WIRE EVAPORATION (PWE) METHOD

Abstract

In the present work, ethylene-glycol (EG) based nanofluids containing TiO 2 nanoparticles were prepared by one-step pulsed wire evaporation (PWE) method. The structural properties of TiO 2 nanoparticles were studied by X-ray diffraction (XRD) method and high resolution transmis- sion electron microscopy (HRTEM). The thermal conductivity of EG-TiO 2 nanofluid increased with TiO 2 volume fraction, and the experimentally measured value of thermal conductivity coincided well with Hamilton-Crosser model.
