Butter on a hot pan: self-regulating dynamics of melt-lubricated sliding
Edoardo Bellincioni, Simon Biermann, Jacco H. Snoeijer +2
When solids melt while sliding down heated inclines, their motion is governed by a complex coupling between heat transfer, phase change, gravity and viscous dissipation. Despite re…
Bubble curtains for noise mitigation: one vs. two
Simon Beelen, Marten Nijhof, Christ de Jong +2
Bubble curtains are widely used to protect marine life from exposure to noise during offshore construction. However, operating a bubble curtain is costly. Therefore optimizing the…
Melting of olive oil in immiscible surroundings: experiments and theory
Pim Waasdorp, Aron H. van den Bogaard, Leen van Wijngaarden +1
We report on the melting dynamics of frozen olive oil in quiescent water for Rayleigh numbers up to . The density difference results in an upward buoyancy-driven flow of liqu…
Surface Tension regularizes the Crack Singularity of Adhesive Contacts
Stefan Karpitschka, Leen van Wijngaarden, Jacco H. Snoeijer
The elastic and adhesive properties of a solid surface can be quantified by indenting it with a rigid sphere. Indentation tests are classically described by the JKR-law when the so…
Energy spectra in turbulent bubbly flows
Vivek N. Prakash, Julian Martinez Mercado, Leen van Wijngaarden +4
We conduct experiments in a turbulent bubbly flow to study the nature of the transition between the classical 5/3 energy spectrum scaling for a single-phase turbulent flow and t…
Oscillations of a gas pocket on a liquid-covered solid surface
Hanneke Gelderblom, Aaldert G. Zijlstra, Leen van Wijngaarden +1
The dynamic response of a gas bubble entrapped in a cavity on the surface of a submerged solid subject to an acoustic field is investigated in the linear approximation. We derive s…
