Abstract
In order to realize the high-efficiency of a process in which milk was filled into a gable top carton with the volume of 1000 mL, the effect of the value of surface tension coefficient on flow dynamics of milk were computationally considered using the Volume-of-Fluid (VOF) method. From numerical results, it was shown that the value of surface tension coefficient largely influenced fluid flows inside the carton in a filing operation process. When a lower surface tension coefficient was used, the dynamic motion of milk became more complicated than that for a higher surface tension coefficient.
