EFFECT OF SURFACE TENSION ON THE LIFETIME OF BULK NANOBUBBLES

摘要

A qualitative analysis of the lifetime of bulk nanobubbles in water is carried out taking into account the Tolman formula, which allows for the curvature dependence of water surface tension. The calculation showed that by increasing the ratio of the Tolman length to the radius of a nanobubble, the lifetime tau increases. However, this effect is rather weak and cannot explain the experimentally observed anomalous long lifetimes of nanobubbles.
