PREPARATION AND CHARACTERIZATION OF COPPER OXIDE NANOPARTICLES AND DETERMINATION OF ENHANCEMENT IN CRITICAL HEAT FLUX

ABSTRACT
The main focus of the present work is to prepare the CuO nanoparticles by economical Sol-Gel method and further to prepare the CuO nanofluid with base fluid as deionised water. The size of nanoparticles is determined by Debye- Scherer formula and size of the particles is conformed 20.4054nm. Critical heat flux characteristics of nanofluid were investigated with different weight concentrations of CuO nanoparticles. The experimental work revealed an increase in critical heat flux value just about 57.26 percent. Surface roughness of heater surface is measured for all weight concentrations of nanofluid which shows increase in Ra value up to some extent is a cause to enhance CHF.
