Dewatering of fibre suspensions by pressure filtration
(AIP PublishingPhysics of Fluids, 2016-06-09)
A theoretical and experimental study of dewatering of fibre suspensions by uniaxial compression is presented. Solutions of a one-dimensional model are discussed and asymptotic limits of fast and slow compression are explored. ...
Detrainment of plumes from vertically distributed sources
(SpringerEnvironmental Fluid Mechanics, 2016-11-22)
We present experimental results demonstrating that, for the turbulent plume from a buoyancy source that is vertically distributed over the full area of a wall, detrainment qualitatively changes the shape of the ambient ...
Hydrodynamic interactions between nearby slender filaments
(IOP PublishingEPL (Europhysics Letters), 2016-11-28)
Cellular biology abound with filaments interacting through fluids, from intracellular microtubules, to rotating flagella and beating cilia. While previous work has demonstrated the complexity of capturing nonlocal hydrodynamic ...
Inelastic scattering of xenon atoms by quantized vortices in superfluids
(American Physical SocietyPhysical Review B, 2016-11-01)
We study inelastic interactions of particles with quantized vortices in superfluids by using a semiclassical matter wave theory that is analogous to the Landau two-fluid equations, but allows for the vortex dynamics. The ...
Torsional Alfvén resonances as an efficient damping mechanism for non-radial oscillations in red giant stars
(Oxford University PressMonthly Notices of the Royal Astronomical Society, 2017-06-01)
Stars are self-gravitating fluids in which pressure, buoyancy, rotation and magnetic fields provide the restoring forces for global modes of oscillation. Pressure and buoyancy energetically dominate, while rotation and ...
On Multi-Level Thinking and Scientific Understanding
(SpringerSpringerAdvances in Atmospheric Sciences, 2017-10)
Professor Duzheng YE’s name has been familiar to me ever since my postdoctoral years at MIT with Professors Jule CHARNEY and Norman PHILLIPS, back in the late 1960s. I had the enormous pleasure of meeting Professor YE ...
Non-abelian 3$D$ bosonization and quantum Hall states
(SpringerJournal of High Energy Physics, 2016-12-01)
Bosonization dualities relate two different Chern-Simons-matter theories, with bosonic matter on one side replaced by fermionic matter on the other. We first describe a more general class of non-Abelian bosonization ...
Einstein–Weyl spaces and near-horizon geometry
(IOP PublishingClassical and Quantum Gravity, 2017-02-02)
We show that a class of solutions of minimal supergravity in five dimensions is given by lifts of three-dimensional Einstein–Weyl structures of hyper-CR type. We characterise this class as most general near-horizon limits ...
Theory of Shape-Shifting Droplets
(American Physical SocietyPhysical Review Letters, 2017-02-24)
Recent studies of cooled oil emulsion droplets uncovered transformations into a host of flattened shapes with straight edges and sharp corners, driven by a partial phase transition of the bulk liquid phase. Here, we explore ...
More Abelian dualities in 2 + 1 dimensions
(SpringerJournal of High Energy Physics, 2017-01-01)
We expand on the recent derivation of 3d dualities using bosonization. We present in some detail a general class of Abelian duals.
