Area of Science:

  • Computational fluid dynamics
  • Multiphase flow modeling
  • Numerical methods

Background:

  • Lattice Boltzmann methods (LBM) are powerful for fluid dynamics.
  • Modeling axisymmetric multiphase flows presents unique challenges.
  • Existing models may lack accuracy or efficiency for these specific geometries.

Purpose of the Study:

  • To develop a novel lattice Boltzmann model for simulating axisymmetric multiphase flows.
  • To incorporate source terms that accurately represent axisymmetric dynamics.
  • To validate the model against known physical phenomena.

Main Methods:

  • A two-dimensional lattice Boltzmann equation was adapted using source terms.
  • Chapman-Enskog multiscale analysis was employed to ensure macroscopic equation recovery.

  • The model was extended to include reduced compressibility effects.

    • Main Results:

    • The model accurately simulates axisymmetric equilibrium drop formation and oscillations.
    • It successfully models the breakup of viscous liquid jets and satellite droplet formation.
    • Simulations of drop collisions show satisfactory agreement with existing data.

    Conclusions:

    • The developed lattice Boltzmann model is effective for axisymmetric multiphase flows.
    • The incorporated source terms accurately capture essential physical forces.
    • The model provides a reliable tool for studying complex multiphase flow phenomena in cylindrical coordinates.
