Circular objects do not melt the slowest in water
Rui Yang, Thijs van den Ham, Roberto Verzicco +2
We report on the melting dynamics of ice suspended in fresh water and subject to natural convective flows. Using direct numerical simulations we investigate the melt rate of ellips…
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…
Enhancing thermal mixing in turbulent bubbly flow by adding salt
Pim Waasdorp, On Yu Dung, Sander G. Huisman +1
The presence of bubbles in a turbulent flow changes the flow drastically and enhances the mixing. Adding salt to the bubbly aqueous flow changes the bubble coalescence properties a…
Scalar transport and nucleation in quasi-two-dimensional starting jets and puffs
You-An Lee, Detlef Lohse, Sander G. Huisman
We experimentally investigate the early-stage scalar mixing and transport with solvent exchange in quasi-2D jets. We inject an ethanol/oil mixture upward into quiescent water, form…
Mixing in confined fountains
You-An Lee, Detlef Lohse, Sander G. Huisman
We have experimentally investigated mixing in highly confined turbulent fountains, namely quasi-two-dimensional fountains. Fountains are formed when the momentum of the jet fluid i…
Mixing and solvent exchange near the turbulent/non-turbulent interface in a quasi-2D jet
You-An Lee, Sander G. Huisman, Detlef Lohse
We inject with jet mixtures of ethanol and dissolved anise oil upward into quiescent water with jet Reynolds numbers, 500<Re_0<810. Nucleation of oil droplets, also known as the ou…
