Multiphase flow dynamics via phase-field modelling

The dynamic behaviour of multiphase flow systems is key in many chemical engineering applications. Phenomena such as phase separation, droplet coalescence and breakup require a fundamental description of the interplay between mixture thermodynamics, flow field, heat and species transport. We apply phase-field modelling coupled to non-equilibrium thermodynamics to describe the dynamics of fluid suspensions and emulsions in complex and unsteady conditions, such as temperature and/or velocity gradients.

Main activities on this topic:

  • finite-element simulations of spinodal decomposition
  • dynamics of mixing/de-mixing in complex flow conditions
  • derivation of constitutive equations of coupled heat and mass transport
