<p>  It is said that surface tension and oxide film affect the flow of melt in aluminum thin casting. Nakae et al. examined the flow pattern of melt in thin plate castings with varied slope angles of the FEM mesh model by direct observation, while Mori et al. examined the flow pattern of melt in thin plate castings with varied atmospheres by direct observation. In this study, our purpose was to reproduce the direct observation results of Nakae et al. and Mori et al. by flow simulation taking into consideration the effects of surface tension and oxide film.</p><p>  Analysis results and experimental results more or less agreed, but the simulation could not reproduce a part of unstable flow in the experiment. We think this difference is due to the breakage of thin and uneven oxide film.</p>
