A team of researchers with the U.S. Geological Survey and the University of Alaska has found that they could estimate the size of bubbles that form from underwater volcanoes by listening to infrasound produced by bubble formation. ...
Engineers at Oregon State University have found a new way to induce and control boiling bubble formation, that may allow everything from industrial-sized boilers to advanced electronics to work better and last longer.

(Phys.org)—Calling it an "Ode to Bubbles," MIT researchers have produced bubbling in sync with Beethoven's Symphony No. 9: Ode to Joy on a surface resembling a piano keyboard. The performance demonstrates the researchers' ...
Researchers at the Institute of Industrial Science, The University of Tokyo, used a sophisticated physical model to simulate the behavior of fluids moving through pipes. By including the possibility of shear-induced bubble ...
