Abstract

In general, this project deals with the theoretical and experimental study of nucleate boiling on nanostructure surfaces. This research involves the design of an experimental apparatus and the results analysis, including the phenomenon visualization. The aim of this study is to analyze the influence of heating surfaces and nanoparticles size on heat transfer coefficient and critical heat flux. Aspects concerning the surface/nanoparticle interaction, related to the deposition of nanoparticles on the heating surface, are thoroughly studied by analysis of the experimental data and visualization of the boiling phenomenon.This study will also involve the characterization of the surfaces tested, through the techniques of Scanning Electron Microscopy (SEM), Atomic Force Microscopy (AFM) and wettability test, before and after the boiling tests, as well as, the size of the nanoparticles deposited.The tests will be performed for deionized water, as working fluids (at atmospheric pressure and at saturation temperature) and, for heating surfaces with and without nanoparticles depositions with different diameters. The contribution of this work is to obtain results of interest to the industry for new refrigeration system components, air conditioning and cooling of electronic components for thermal control of machines, where the heat fluxes to be removed are higher than those provided by single-phase systems.
