Expérimental
We are interested in the case of schools of fish and more particularly in their evacuation through an opening of a size comparable to the size of the fish. We have recently shown that the escape of fish is analogous to that of bubbles. We would like to further explore this analogy and its limits. The aim of the internship will be to analyze the statistics of evacuation time intervals, in the same way as we did for fish, and see whether the model proposed for fish is valid for bubbles. The physical questions are many and open: how intermittent is bubble evacuation? Can we observe blocking phenomena such as those seen with active particles or grains? What are the interactions between slits and their consequences on bubble evacuation rates?
