Diapycnal mixing in layered stratified plane Couette flow quantified in a tracer-based coordinate
(Cambridge University PressJournal of Fluid Mechanics, 2017-07)The mixing properties of statically stable density interfaces subject to imposed vertical shear are studied using direct numerical simulations of stratified plane Couette flow. The simulations are designed to investigate ...

Dynamics of laterally confined marine ice sheets
(Cambridge University PressJournal of Fluid Mechanics, 2016-02-03)We present an experimental and theoretical study of the dynamics of laterally confined marine ice sheets in the natural limit in which the long, narrow channel into which they flow is wider than the depth of the ice. A ...

Gravity current propagation up a valley
(Cambridge University PressJournal of Fluid Mechanics, 2015-01-10)The advance of the front of a dense gravity current propagating in a rectangular channel and V-shaped valley both horizontally and up a low slope is examined through theory, full-depth lock-release laboratory experiments ...

Lubricated viscous gravity currents
(CUPJournal of Fluid Mechanics, 2015-02-10)We present a theoretical and experimental study of viscous gravity currents lubricated by another viscous fluid from below. We use lubrication theory to model both layers as Newtonian fluids spreading under their own weight ...

Self-similar mixing in stratified plane Couette flow for varying Prandtl number
(Cambridge University PressJournal of Fluid Mechanics, 2017-06-10)We investigate fully developed turbulence in stratified plane Couette flows using direct numerical simulations similar to those reported by Deusebio et al. (J. Fluid Mech., vol. 781, 2015, pp. 298-329) expanding the range ...
