Electrosprays can exhibit a new chaotic astable regime, challenging the sudden transition to the cone-jet regime. This finding offers a broader nonlinear dynamics view for classifying electrospray axial regimes.

Area of Science:

  • Nonlinear Dynamics
  • Fluid Dynamics
  • Physics

Background:

  • Astable regimes are prevalent in nonlinear systems, including electrooptic devices and cardiac rhythms.
  • Electrosprays commonly display three axial regimes: dripping, pulsating, and cone-jet.
  • The transition from pulsating to cone-jet regimes is typically considered abrupt with increased spray current.

Purpose of the Study:

  • To investigate an alternative pathway for electrospray regime transitions.
  • To introduce and characterize a novel chaotic astable regime in electrosprays.
  • To expand the understanding of electrospray dynamics using nonlinear dynamics principles.

Main Methods:

  • Observation and analysis of electrospray behavior under varying conditions.
  • Application of nonlinear dynamics theory, specifically subcritical Andronov-Hopf bifurcation.

  • Modeling the astable regime as transitions between limit cycles and fixed points.

    • Main Results:

    • Identification of a previously unrecognized chaotic astable regime in electrosprays.
    • Demonstration that electrosprays can transition to the cone-jet regime via this astable path.
    • Explanation of the astable regime as noise-induced transitions between pulsating and cone-jet dynamics.

    Conclusions:

    • The transition between pulsating and cone-jet electrospray regimes is not always sudden.
    • A chaotic astable regime, driven by noise, provides a new perspective on electrospray dynamics.
    • This discovery enables a more comprehensive classification of electrospray axial regimes based on nonlinear dynamics.
