マイクロ液滴の表面張力振動との比較による表面張力計算モデルの妥当性評価

抄録

Micro-meter sized small droplet can be generated with a capillary bridge breakup method. With this method, surface tension oscillation of the droplet is spontaneously excited from the initial rod like shape. Comparing with the oscillation, it can assess the validation of numerical simulation with surface tension model. Numerical simulation of the droplet's oscillation is conducted with SPH method with continuum surface tension force. Time evolution of droplet’ silhouette shows good agreement between the SPH simulation and the experiment. And the frequency of the oscillation also agrees well.
