Tech engineers have shed light on what happens to a nearby particle when
bubbles burst.
Sunghwan Jung, an assistant professor of biomedical
engineering and mechanics in the College of Engineering, has discovered new
information about a phenomenon called cavitation, the process of bubble
formation in a fluid like water.
These bubbles eventually collapse under the pressure of the
surrounding fluid, sending out pressure waves that can affect anything nearby.
For example, shrimp use cavitation bubbles to hunt because the waves can kill
small fish.
