The Importance of the Unsteady Kutta Condition when Modelling Gust-Aerofoil Interaction
(ElsevierJournal of Sound and Vibration, 2016-06-01)
The Kutta condition is applied to aerofoils with sharp trailing edges to allow
for viscous effects to be considered within a simplified system of equations
that are inviscid. This paper discusses in detail the inclusion ...
Numerical Relativity and High Energy Physics: Recent Developments
(World ScientificInternational Journal of Modern Physics D, 2016-07-15)
We review recent progress in the application of numerical relativity techniques to astrophysics
and high-energy physics. We focus on recent developments regarding the spin
evolution in black hole binaries, high-energy black ...
Gravitoturbulence in magnetized protostellar discs
(Oxford University PressMonthly Notices of the Royal Astronomical Society, 2016-05-11)
Gravitational instability (GI) features in several aspects of protostellar disc evolution, most notably in angular momentum transport, fragmentation, and the outbursts exemplified by FU Ori and EX Lupi systems. The outer ...
ππ→πγ$^{∗}$ amplitude and the resonant ρ→πγ$^{∗}$ transition from lattice QCD
(American Physical SocietyPhysical Review D, 2016-06-10)
We present a determination of the P-wave ππ→πγ$^{⋆}$ transition amplitude from lattice quantum chromodynamics. Matrix elements of the vector current in a finite volume are extracted from three-point correlation functions, ...
Quantifying eddy feedbacks and forcings in the tropospheric response to stratospheric sudden warmings
(American Meteorological SocietyJournal of the Atmospheric Sciences, 2016-08-26)
The equatorward shift of the zonal mean midlatitude tropospheric jet following a stratospheric sudden warming in a comprehensive, stratosphere-resolving model is found to be well quantified by a simple model, due to Lorenz ...
A comparative perspective on the evolution of Romance clausal structure
(John Benjamins PublishingDiachronica, 2016-12-19)
This article presents a comparative analysis of the diachronic evolution of Romance clausal structure from Classical Latin through to the late medieval period, with particular reference to the Verb Second (V2) property. ...
The power spectrum and bispectrum of inflation and cosmic defects
(University of CambridgeDepartment of Applied Mathematics and Theoretical PhysicsGonville and Caius College, 2016-06-28)
Much of the recent progress in cosmology has come from studying the power spectrum of the cosmic microwave background (CMB). The latest results from the Planck satellite confirmed that the inflationary paradigm with the ...
Stochastic cycle selection in active flow networks
(National Academy of Sciences of the USAProceedings of the National Academy of Sciences, 2016)
Active biological flow networks pervade nature and span a wide
range of scales, from arterial blood vessels and bronchial mucus
transport in humans to bacterial flow through porous media or
plasmodial shuttle streaming in ...
Directed collective motion of bacteria under channel confinement
(Institute of PhysicsNew Journal of Physics, 2016-07-01)
Dense suspensions of swimming bacteria are known to exhibit collective behaviour arising from the
interplay of steric and hydrodynamic interactions. Unconfined suspensions exhibit transient,
recurring vortices and jets, ...
Tunnelling effects for acoustic waves in slowly varying axisymmetric flow ducts
(ElsevierJournal of Sound and Vibration, 2016-06-22)
The multiple-scales Wentzel–Kramers–Brillouin (WKB) approximation is used to model the propagation of acoustic waves in an axisymmetric duct with a constriction in the presence of mean flow. An analysis of the reflection ...
