Turbulence

RANS: standard K-E model, with:

  • Anisotropic (TLVA) & Algebraic Stress Modeling (ASM)
  • Wall functions, two-layer & Low-Re modeling
  • Langevin equation for particle dispersion

LES for single & multiphase flow:

  • Smagorinsky & Dynamic SGS models
  • Modified SGS models for two-phase flow
  • Two-layer approach (LES & one-equation modeling)

Two phase flow

  • Explicit and implicit solvers
  • Unsteady Navier-Stokes equations
  • Eulerian field formulation with inertial settling
  • Level Set and VOF methods for interface tracking
  • Additional solving for density and specific heat equations
  • Particle Lagrangian tracking one- & two-way coupling
  • Two-phase flow with heat transfer
  • Phase change: various models & interface flux integration
  • Wetting: static contact angle & triple line dynamics
