The following numerical simulations are conducted by using

  • The CLSVOF (coupled level set and volume-of-fluid) method
  • The THINC/WLIC (tangent of hyperbola for interface capturing/weighted line interface calculation) scheme
  • The multi-moment methods (CIP-CSL and VSIAM3)
  • The density-scaled CSF (continuum surface force) model within a balanced force formulation
