Natural oscillations of a sessile drop on flat surfaces with mobile contact lines
Jordan Sakakeeny, Yue Ling
Abstract
The sessile drop oscillation with free contact lines (the contact angle remains constant when the contact line moves) is investigated through numerical and theoretical analysis. A parametric study is carried out to characterize the effects of contact angle and Bond number on the frequencies for the first and high-order modes. An inviscid theoretical model is developed to provide an explicit expression for the dominant first mode frequency.
