New bubbling mechanism discovered in physics
The Inside Story.This paper examines numerically the validity of some asymptotic-theory predictions such as the existence of two resonant radii and a limit size for a given sound amplitude and frequency. For an optimum polymer concentration, the interfacial effects dampen short-wavelength waves, which intensifies the focusing of . We perform force balance and scaling analysis to develop a model to predict the maximum jumping height of bubbles.
