An Experimental Determination of Thermal Conductivity and Viscosity of BioGlycol/water based TiO2 Nanofluids

Nanofluid as a new brand of cooling fluid consisting of nanometer-sized particles dispersed in base fluid. In this study, nanofluids have been prepared by dispersing TiO2 nanoparticles in different base fluids such as 20:80% and 30:70% by volume of BioGlycol (BG)/water (W) mixtures. Thermal conducti...
