In general, this project deals with the theoretical and experimental study of nucleate boiling using different nanofluids as working fluids. 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 nanofluids on heat transfer coefficient and critical heat flux. Aspects concerning the formation and growth of vapor bubbles, as well as, drying out effect related to the interaction surface/nanofluid, are thoroughly studied by analysis of the experimental data and visualization of the boiling phenomenon. This study will also involve the nanofluid characterization, 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. The tests will be performed using, as working fluids, deionized water and the nanofluids: Al2O3-water e Fe2O3-water (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.
