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 ...
Conditional sampling of a high Péclet number turbulent plume and the implications for entrainment
(Cambridge University PressJournal of Fluid Mechanics, 2017-07-25)
We present simultaneous two-dimensional velocity and scalar measurements on a central vertical plane in an axisymmetric pure turbulent plume. We use an edge-detection algorithm to determine the edge of the plume, and compare ...
