Area of Science:

  • Fluid Dynamics
  • Instability Phenomena
  • Multiphase Flow

Background:

  • Understanding fluid jet stability is crucial for various industrial applications.
  • Low density and viscosity fluid jets in coflowing liquids exhibit complex instability behaviors.
  • Previous studies have not fully explored the parametric space of Weber and Reynolds numbers for such systems.

Purpose of the Study:

  • To investigate the stability of low density and viscosity fluid jets in unbounded coflowing liquids.
  • To identify the critical conditions leading to a transition in instability from absolute to convective.
  • To develop and validate a model for predicting fluid jet breakup and bubbling.

Main Methods:

  • Parametric analysis across a range of low to high Weber and Reynolds numbers.

Related Experiment Videos

  • Theoretical modeling of fluid jet instability.
  • Experimental validation of the proposed model using fluid jet experiments.

    • Main Results:

    • The presence of finite density and viscosity within the hollow jet induces a transition from absolute to convective instability.
    • This transition occurs at a finite Weber number, irrespective of the Reynolds number.
    • Below the critical Weber number, absolute instability leads to local jet breakup and subsequent bubbling.

    Conclusions:

    • A critical Weber number governs the transition of fluid jet instability in coflowing liquids.
    • The findings provide a predictive framework for fluid jet breakup and bubbling phenomena.
    • Experimental data confirm the theoretical model's accuracy in describing jet stability.
