Study of flow boiling heat transfer characteristics of critical heat flux using carbon nanotubes and water nanofluid

Flow boiling heat transfer characteristics using a new nanofluid, multi-walled carbon nanotubes (MWCNTs)/pure water were investigated in a horizontal tube under atmospheric pressure. In order to prepare nanofluid, gum Arabic (GA) as a surfactant and MWCNTs nanoparticles were used in the ratio 1:1 with concentrations of 0.001 and 0.01% by mass, and its stability was determined by measuring zeta potential. During the experiments, detailed...
