Researchers explored air bubble formation in glycerol solutions, observing distinct bubbling regimes and the emergence of antibubbles. These phenomena were linked to air flow rate and intermittent dynamics.

Area of Science:

  • Fluid dynamics
  • Rheology
  • Surface science

Background:

  • Bubble formation is crucial in multiphase flow systems.
  • Understanding bubble dynamics in non-Newtonian fluids like glycerol solutions is complex.
  • Previous studies have focused on simpler liquid systems.

Purpose of the Study:

  • To investigate the formation dynamics of air bubbles in aqueous glycerol solutions.
  • To characterize different bubbling regimes based on air flow rate.
  • To explore the conditions leading to antibubble formation.

Main Methods:

  • Experimental study of air bubble emission from a submerged nozzle.
  • Systematic variation of glycerol solution viscosity.
  • Analysis of bubble formation using air flow rate as a control parameter.

  • Time-series analysis of the intervals between successive bubbles.
  • Emulation of bubbling coalescence using simple map models.
  • Observation and analysis of antibubble formation.

    • Main Results:

    • Distinct bubbling regimes were identified and described.
    • The time between successive bubbles was used as a dynamical variable.
    • Bubbling coalescence phenomena were successfully emulated with simple maps.
    • Antibubbles, air shells around liquid drops, were observed.
    • Antibubbling conditions were found to correlate with an intermittent dynamical regime.

    Conclusions:

    • The study provides insights into the complex dynamics of bubble formation in viscous fluids.
    • Glycerol concentration significantly influences bubble formation and regime transitions.
    • Antibubble formation is linked to specific intermittent flow conditions, offering new avenues for research.
