Area of Science:

  • Physics
  • Fluid Dynamics
  • Microfluidics

Background:

  • Microfluidic and lab-on-a-chip systems offer confined environments for studying fluid phenomena.
  • Laser-induced cavitation is a method for generating localized disturbances in liquids.
  • Understanding bubble dynamics in confined spaces is crucial for microfluidic applications.

Purpose of the Study:

  • To investigate cavitation bubble dynamics in microfluidic channels.
  • To analyze the formation and characteristics of liquid jets generated by collapsing cavitation bubbles.
  • To explore the influence of geometry on cavitation jetting behavior.

Main Methods:

  • Generating cavitation bubbles using a pulsed laser in microfluidic channels filled with light-absorbing liquid.
  • Observing bubble expansion and collapse dynamics using high-speed imaging.
  • Comparing experimental bubble dynamics with a two-dimensional Rayleigh model.
  • Measuring planar flow fields during bubble collapse.
  • Analyzing jetting phenomena near channel walls and in complex geometries (triangles, squares).

Main Results:

  • Pancake-shaped cavitation bubbles were observed to expand and collapse radially in a 20 microm thick, 1 mm wide channel.
  • Bubble dynamics showed agreement with a two-dimensional Rayleigh model.
  • When near a wall, bubbles generated a focused liquid jet, similar to axisymmetric jetting.
  • The jet flow induced two counter-rotating vortices, leading to high-velocity liquid stirring.
  • In triangular and square geometries, the number of observed liquid jets correlated with the number of nearby boundaries.

Conclusions:

  • Laser-induced cavitation in microfluidic systems generates directional liquid jets and vortices.
  • The geometry of the microchannel significantly influences the cavitation jetting phenomenon.
  • This controlled jetting and stirring mechanism has potential applications in microfluidic mixing and manipulation.
