摘要:
A shock tube is used to investigate the bubble dynamics under sudden decrease of ambient pressure. Both the oscillating and monotonously growing bubbles were simultaneously observed. Theoretical approach is based on Considering the linear approximation of these equations for the quasiequilibrium state, two critical Weber numbers are defined. They enable one to predict the following modes of the bubble expansion: (i) unbounded growth, (ii) asymptotic growth to limited volume and (iii) attenuated oscillations, depending on the pressure force,viscosity and compressibility of the liquid.
