OBJECTIVE: Liquid/Gaz Interface Simulations

Imag1.png


Describe the interface motion precisely Fleche vert.png Level Set Method


Handle jump conditions at the interface without artificial smoothing Fleche vert.png Ghost Fluid Method


Respect mass conservation Fleche vert.png VOF Method


Solve incompressible Navier Stokes equations Fleche vert.png Projection Method




Fleche roueg.png Archer is a 3D incompressible Navier Stokes solver with Level Set-Ghost Fluid-VOF coupling and MPI parallelization


NUMERICS

  • Cartesian mesh
  • Mac grid (velocities on cell boundaries)
  • WENO 5 scheme for convective terms, Adams Bashforth or RK3 or split algorithm in time
  • Multigrid algorith for preconditionning Conjugate Gradient Method in Poisson equation solver
  • Ghost Fluid method for variable discontinuities at the interface
  • CLSVOF for mass conservation
  • MPI parallelization
