Abstract
A theory is proposed on the creation of microbubbles in liquids by ionizing particles. A thermodynamic point of view allows one to specify the conditions required for the growth of the gaseous embryos statistically present in liquid. In the case of aerated water, the process shows the existence of an energy threshold for the production of 1-μ-radius bubbles as required for ultrasonic cavitation; the theoretical values of particle energy agree with experimental results. Also proposed is a mechanism for one qualitative determination of the stable existence of microbubbles in water.Keywords
