This research aims to study the mechanism and condition for the large bubble formation using copper as a metal heat transfer surface and compare it with the experimental results using ITO (Indium Tin Oxide) as the heat transfer surface. Based on previous studies, the mechanism of ITO surface has been determined and can provide certain thermal conductivity. Through bubble visualization and void fraction measurement experiments, the similarity and difference in the large bubble formation mechanism under the subcooled flow boiling experiments between copper and ITO heat transfer surfaces are verified.
