Ice melting in an oscillatory flow
Sofía Angriman, Tobias de Buck, Roberto Verzicco +1
We investigate the melting dynamics of an ice disk subjected to an external oscillatory flow using two-dimensional direct numerical simulations, in the absence of buoyancy, varying…
The effects of salinity and inclination on the morphology of melting ice
Tomás J. Ferreyra Hauchar, Detlef Lohse, Sander G. Huisman
The salinity of water and the slope of ice significantly influence the melt rate and surface morphology of ice, both highly relevant in the context of glacier and iceberg melting i…
The moment of inertia tensor of an oloid
Sander G. Huisman
The oloid is defined as the convex hull of two unit circles in perpendicular planes, each passing through the center of the other. In this paper we derive an analytical expression…
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…
Settling of chiral particles in a turbulent flow
Mees M. Flapper, John E. Sader, Detlef Lohse +1
Chiral particles are experimentally investigated while settling inwater with various turbulence intensity levels. The locations and orientations of the particles are tracked over t…

We report on Lagrangian flow statistics from experimental measurements of homogeneous isotropic turbulence. The investigated flow is driven by 12 impellers inside an icosahedral vo…
Salts promote or inhibit bubbly drag reduction in turbulent Taylor-Couette flows
Luuk J. Blaauw, Detlef Lohse, Sander G. Huisman
Bubbly drag reduction is considered as one of the most promising techniques to reduce the energy consumption of marine vessels. With this technique bubbles are injected under the h…
