Liquid-body resonance while contacting a rotating superhydrophobic surface

摘要: We advance a scheme in which liquid body on stationary tip contact with rotating superhydrophobic surface is able to maintain resonance primarily from stick-slip events. With tip-to-surface spacing the range $2.73 \le h < 2.45$ mm for volume of 10 μL, was found exhibit independent speed drum. The mechanics were be due surface-tension-controlled vibration mode based natural frequency values determined. $2.45 2.15$ imposed length vary rotation SH This events being generate higher energy fluctuations causing liquid-solid areas since almost oblate spheroid shape had intrinsically energies. resulted perturbations frequency- and amplitude-modulated over lower carrier. These findings have positive implications microfluidic sensing.
