Abstract
The thermal behavior of bubbles intensively oscillating in liquids is still not well understood. The reason is a relative large complexity of this phenomenon and difficulties associated with obtaining suitable experimental data. In theoretical analysis dealing with low intensity gas bubble oscillations it is usually assumed that the bubbles behave adiabatically or isothermally [1]. However, not much is known about high intensity oscillations of vapor bubbles. Based on analysis of experimental data it will be shown in this work that the adiabatic assumption cannot be used when dealing with spark generated bubbles.File in questo prodotto:
