Coupled Rayleigh--Taylor and Faraday instabilities in vertically vibrated cylindrical containers
Tianyi Chu, Benjamin Wilfong, Timothy Koehler +2
Interfacial instabilities govern the mixing in confined multiphase flows. Yet, the two mechanisms that drive them are usually studied independently: the pressure-gradient-driven Ra…

Energy dissipation mechanisms in an acoustically-driven slit
Haocheng Yu, Tianyi Chu, Spencer H. Bryngelson
We quantify how incident acoustic energy is converted into vortical motion and viscous dissipation for a two-dimensional plane-wave passing through a slit geometry. We perform dire…

Competing Mechanisms at Vibrated Interfaces of Density-Contrast Fluids
Tianyi Chu, Benjamin Wilfong, Timothy Koehler +2
Fluid--fluid interfacial instability and subsequent fluid mixing are ubiquitous in nature and engineering. The hydrodynamic instability of fluid interfaces has long centered on the…
