Efficient mixing in stratified flows: experimental study of a Rayleigh-Taylor unstable interface within an otherwise stable stratification
(Cambridge University PressJournal of Fluid Mechanics, 2014-09-09)
Boussinesq salt-water laboratory experiments of Rayleigh–Taylor instability (RTI) can achieve mixing efficiencies greater than 0.75 when the unstable interface is confined between two stable stratifications. This is much ...
On the thermodynamic boundary conditions of a solidifying mushy layer with outflow
(CUPJournal of Fluid Mechanics, 2014-11-27)
The free-boundary problem between a liquid region and a mushy layer (a reactive porous medium) must respect both thermodynamic and fluid dynamical considerations. We develop a steady two-dimensional forced-flow configuration ...
A physically based parameterization of gravity drainage for sea-ice modelling
(Wiley on behalf of the American Geophysical UnionJournal of Geophysical Research: Oceans, 2014-09-02)
We incorporate a physically derived parameterization of gravity drainage,
in terms of a convective upwelling velocity, into a one-dimensional, thermodynamic sea-
ice model of the kind currently used in coupled climate ...
Enhanced active swimming in viscoelastic fluids
(IOP PublishingEurophysics Letters, 2014-11-05)
Swimming microorganisms often self-propel in fluids with complex rheology. While past theoretical work indicates that fluid viscoelasticity should hinder their locomotion, recent experiments on waving swimmers suggest a ...
Generations: three prints, in colour
(SpringerJournal of High Energy Physics, 2014-10-07)
We point out a somewhat mysterious appearance of SUc(3) representations, which exhibit the behaviour of three full generations of standard model particles. These representations are found in the Clifford algebra ℂl(6), ...
