The dynamics of microscopic bubbles in viscous insulating liquids

摘要: The dynamics of microscopic bubbles in low viscosity insulating liquids has been widely investigated. It shown that the bubble motion (growth, collapse, and rebounds) such is governed by inertial forces. In this paper, results an experimental study viscous (μ≥3 mPl) are presented. that, according to conditions (injected energy, liquid viscosity, applied pressure), greatly modified. For example, no rebound observed higher (e.g., Napvis XD110, μ=83.5 mPl) and, for a given injected ratio expansion time its implosion drops with increasing viscosity. then Moreover, transition from regime one experimentally (as far as present authors aware) first time. This ca...
