AB - 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.
