Summary on Grant Application Form
Horizontally vibrated interfaces exhibit a rich variety of interesting dynamics which have been surprisingly neglected to date. Distinct oscillatory shear-driven instabilities of liquid-liquid interfaces, characterised by the formation of a steady, spatially-periodic relief, have been reported for liquids of similar viscosities and in the limit of large viscosity ratios. Uncovering the relation between these phenomena is the primary aim of this proposal. An additional interesting factor is that the deformed interface can become prone to breakup, particularly in low viscosity fluids, which significantly enriches the dynamics. In this proposal, a programme is outlined to utilise a benchmark experimental system, designed and manufactured over the past two years, to gain an extensive understanding of the effect of horizontal vibration on interfacial dynamics. insights into the basic mechanisms of the instabilities will be derived using the powerful combination of theory and experiments. The specific goals are:- Establish the influence of the viscosity ratio on the stability of the interface;- Characterise the conditions and processes by which interface rupture occurs under accelerated and periodic shear.
