Universality of Tip Singularity Formation in Freezing Water Drops
Alvaro G. Marin, Oscar R. Enriquez, Philipe Brunet +2
A drop of water deposited on a cold plate freezes into an ice drop with a pointy tip. While this phenomenon clearly finds its origin in the expansion of water upon freezing, a quan…
Exploring droplet impact near a millimetre-sized hole: comparing a closed pit with an open-ended pore
Rianne de Jong, Oscar R. Enríquez, Devaraj van der Meer
We investigate drop impact dynamics near both closed pits and open- ended pores experimentally. The resulting impact phenomena differ greatly for a pit or a pore. For the first, we…
Growing bubbles in a slightly supersaturated liquid solution
Oscar R. Enríquez, Christian Hummelink, Gert-Wim Bruggert +4
We have designed and constructed an experimental system to study gas bubble growth in slightly supersatu- rated liquids. This is achieved by working with carbon dioxide dissolved i…
Taming Acoustic Cavitation
David Fernandez Rivas, Bram Verhaagen, Oscar R. Enriquez +4
In this fluid dynamics video we show acoustic cavitation occurring from pits etched on a silicon surface. By immersing the surface in a liquid, gas pockets are entrapped in the pit…
Freezing singularities in water drops
Oscar R. Enriquez, Alvaro G. Marin, Koen G. Winkels +1
In this fluid dynamics video we show how a drop of water freezes into a singular shape when deposited on a cold surface. The process of solidification can be observed very clearly…
Collapse of a non-axisymmetric, impact-created air cavity in water
Oscar R. Enriquez, Ivo R. Peters, Stephan Gekle +3
The axisymmetric collapse of a cylindrical air cavity in water follows a universal power law with logarithmic corrections. Nonetheless, it has been suggested that the introduction…
