In general, this project deals with the theoretical and experimental study of nucleate boiling on nanostructured 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 nanostructured surfaces and the gap size on heat transfer coefficient and critical heat flux. Aspects concerning the drying out, related to the gap size effect, 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; the study of different nanofluids concentrations, as well as, the size of the nanoparticles deposited. A deep analysis is necessary in the case of confined nucleate boiling in order to perfect its use as an intensification technique and also to minimize the risks associated with confinement when it is imposed on a design because it can cause problems linked to the premature occurrence critical heat flux, which represents the limit of operation of the system in the nucleate boiling regime. The tests will be performed for different working fluids, water and HFE7100 (at atmospheric pressure and at saturation temperature) and, for heating surfaces of copper. 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.
