Abstract
Dynamic surface tension is one of the most important physical properties for interfacial phenomena of many applications. A proposal on the measurement method of dynamic surface tension was found in previous research, which uses local deformations in the droplet surface. To clarify the local flow in the tiny droplet, we investigated the deformation of shell liquid of the droplet on the vibrating plate using 2D finite element method. The gas-liquid droplet surface area was calculated locally in each section of radial angle under given apparent gravity. We found that the interface of the local droplet deformation can be related to the local surface tension.
