摘要: We report gravity oscillations of a liquid column partially immersed in bath liquid. stress some peculiarities this system, namely (i) the fact that mass oscillator constantly changes with time; (ii) singular character beginning rise, for which is zero; (iii) sources dissipation found to be dominated at low viscosity by entrance (or exit) effects, leading long-range damping oscillations. conclude qualitative descriptions second-order phenomenon, eruption jet rise.
