A fluid mechanical model for two-phase flows

  • Thomas Blesgen Universität Leipzig

Abstract

A modified Allen- Cahn equation is combined with the compressible Navier- Stokes system. After a physically motivated modification of the stress tensor, for the resulting equations the second law of thermodynamics is valid. The model can be used to describe the forming of gas phases in a flowing liquid.
