In this work, we study the resonance behavior of mechanically oscillated, sessile water drops. By mechanically oscillating sessile drops vertically and within prescribed ranges of frequencies and amplitudes, a rich collection of resonance modes are observed and their dynamics subsequently investigated. We first present our method of identifying each mode uniquely, through association with spher...

2014 Some experimental results on the macroscopic spreading of hanging and sessile drops on smooth surfaces are presented. The results for sessile drops nicely corroborate the main aspects of the spreading theory of de Gennes and Joanny. However, it is shown that one assumption of the theory, namely the retainment of a self-similar shape during spreading, which is approximately true for sessile...

A new method, the sessile drop accelerometry (SDACC) for the study and measurement of the 7 interfacial energies of solid-liquid-gas systems, is tested and discussed in this study. The laboratory 8 instrument and technique –a combination of a drop shape analyzer with high-speed camera and a 9 laboratory drop towerand the evaluation algorithms, were designed to calculate the interfacial energies...

A new technique, the sessile drop accelerometry (SDACC) for the study and measurement of the interfacial energies of solid-liquid-gas systems is tested and discussed in this study. The instrument –a combination of a goniometer with high speed camera and a laboratory drop towerand the evaluation method, were designed to evaluate the interfacial energies as a function of the geometrical changes o...
