This study analyzes the energy and shape of three-dimensional bubble clusters. Findings improve bubble cluster growth laws and explore packing limits for deformable bubbles.

Area of Science:

  • Physics, Materials Science, Fluid Dynamics

Background:

  • Understanding bubble cluster dynamics is crucial for various scientific and industrial applications.
  • Existing growth laws for bubble clusters require refinement, particularly in three-dimensional arrangements.

Purpose of the Study:

  • To calculate the energy and optimal shape of three-dimensional clusters of equal-volume bubbles surrounding a central bubble.
  • To refine existing growth laws for three-dimensional bubble clusters by analyzing surface area and bubble pressures.
  • To investigate the maximum number of deformable bubbles that can pack around a central bubble, adapting the classical 'kissing problem'.

Main Methods:

  • Computational modeling and simulation to determine cluster energy and shape.
  • Calculation of surface area and internal bubble pressures for packed clusters.
