摘要：

In order to obtain the ffundmantal knowledge of free-surfaces flows under conditions, the unsteady deformation of liquid surface in cylindrical vessles were expermentally observed with a drop tower. Main concern was placed on the dynamic behavior of the liquid driven by surfaces force and wetting. the deformation of the ethanol surface driven by surface tension was confirmed to be governed by the similatiy rule described by weber number. even when the operating fluid was changed to ethyl benzene or Fc-77, the scaled displacement has good correlation with the scaled time. Among the operating fluids with the similar values of advancing contract angle, the similartiy law was well established the present cases.
