A new hierarchical model for two-phase flow combines macroscopic hydrodynamics and interfacial dynamics. Simulations validate the model, demonstrating its application to colliding droplets under shear flow.

Area of Science:

  • Fluid dynamics
  • Computational physics
  • Materials science

Background:

  • Two-phase flow phenomena are crucial in various scientific and engineering fields.
  • Existing models often struggle to capture both macroscopic and microscopic interfacial behaviors simultaneously.
  • Understanding droplet dynamics under flow is essential for processes like emulsification and microfluidics.

Purpose of the Study:

  • To develop a novel hierarchical model for simulating two-phase flow.
  • To integrate macroscopic hydrodynamic and microscopic interfacial dynamics within a unified framework.
  • To validate the model's predictive capabilities through numerical simulations.

Main Methods:

  • Construction of a two-layered hierarchical model.
  • Macroscopic hydrodynamics governed by the Navier-Stokes equations.
