Effect of ZrO₂ Nanoparticle Deposited Layer on Pool Boiling Heat Transfer Enhancement

Abstract

Nanofluid preparation and its deposition on metallic surfaces are in wide practice due to their enhancement capability in the pool boiling heat transfer. The effect of zirconia nanoparticles coated layer on pool boiling heat transfer has been investigated with de-ionized water. The turbidity, viscosity and stability test are conducted, and confirmed a better dispersion of nanoparticles. The synthesized zirconia nanofluid is deposited by nanofluid boiling nanoparticle technique at different concentrations on three copper samples. The conventional characterization techniques confirm the better structural behavior of the coating. The obtained results of non-coated copper sample fits well with Rohsenow correlation, which signifies the reliability and stability of the obtained results. Experimental results shows that sample with 200 nm coating thickness and 227 nm surface roughness improved the heat transfer coefficient by 31.52% compared to non-coated copper sample. The bubble behavior of the same has the highest velocity and lower bubble diameter compared to other at 785 kW/m² of heat flux. Hence by this experimentation, it is found that the effect of surface characteristics of the zirconia coated layer on the copper surface enhances the pool boiling heat transfer coefficient at the maximum coating thickness and surface roughness by the considered coating technique.
