We use bubble rafts for
multiple different studies.
Most recent studies
– using a bubble raft to look at material failure under expansion. This
series of movies shows a bubble raft being pulled apart under various
This initial movie was
our first one that showed fracture:
For this series of
images, the bubble size ~0.7mm and the barriers are moving at 1.3 cm/s
This first set is for
This next set is for
polydisperse rafts. The images are the same scale.
This next set of movies
applies an oscillatory compression/expansion to the raft:
We also study bubbles in
channel flows. These are very preliminary results.
