Oscillation of the velvet worm slime jet by passive hydrodynamic instability
The rapid squirt of a proteinaceous slime jet endows velvet worms (Onychophora) with a unique mechanism for defence from predators and for capturing prey by entangling them in a disordered web that immobilizes their target. ...
Pushing amplitude equations far from threshold: application to the supercritical Hopf bifurcation in the cylinder wake
(IOP Publishing, 2016)
The purpose of this review article is to push amplitude equations as far as possible from threshold. We focus on the Stuart-Landau amplitude equation describing the supercritical Hopf bifurcation of the flow in the wake ...
A perspective on oil-whirl using two orthogonal coupled oscillators
(2016-03-01)
It has been known for many years that rotating machinery with hydrodynamic oil-film bearings can exhibit oil-whirl instability, where the unidirectional oil-film force acts on the rotor causing it to vibrate at a natural ...
Convective instabilities in thermoviscoelastic micropolar fluids.
(2011-10-13)
The infinitesimal instabilities in plane horizontal layer of viscoelastic micropolar fluid under uniform heating are investigated. The micropolar fluid is a fluid each particle of which has a six degrees of freedoms of ...
Lower bound on the electroweak wall velocity from hydrodynamic instability
(Iop Publishing, 2015-03)
The subsonic expansion of bubbles in a strongly first-order electroweak phase transition is a convenient scenario for electroweak baryogenesis. For most extensions of the Standard Model, stationary subsonic solutions (i.e., ...

Radiation hydrodynamical turbulence in protoplanetary disks: Numerical models and observational constraints
(IOP Publishing Ltd, 2017)
Planets are born in protostellar disks, which are now observed with enough resolution to address questions about internal gas flows. Magnetic forces are possibly drivers of the flows, but ionization state estimates suggest ...
