| Summary: | 碩士 === 國立中山大學 === 機械與機電工程學系研究所 === 106 === Liquid sloshing problem is one of the major issue in our life. For instance, tank truck for land transportation, storage tank for sea vessels or oil storage tanks causing serious disasters due to earthquakes, cause many inconveniences and disasters. In recent years, many researchers investigated liquid sloshing problems by using numerical simulations or experiments. However, there are too much assumptions need to be made in simulation, and which results can’t fully describe the real situation. On the other hand, in experiment, most researchers investigated the liquid sloshing problems by taking two-dimensional photos from the side of the tank. But liquid sloshing profile is a three-dimensional phenomenon. Therefore, this study selected the cylindrical container to come closer to reality. This study adopted digital image correlation technique in order to measure the three-dimensional surface profile of a sloshing liquid. When cylindrical container sloshing, the waveform is complex, and its height are inconsistent along each axis. There are only three-dimensional surface profile can describe the real situation when sloshing. This study adopted two container(diameter:105mm、diameter:130mm), and three different liquid depth(30mm、45mm、60mm), and two liquid(water、mixed solution), to compare the effect on surface profile.
