Numerical simulation of droplet splashing (UK-Fluids Network Video Competition Award)

April 28, 2019 By Kensuke Yokoi Leave a Comment

Video

A numerical simulation of droplet splashing on a super hydrophobic substrate at 1,000,000 fps. The video won the video category of the UK Fluids Network video competition. https://fluids.ac.uk/

Numerical methods

The numerical methods which are used for this numerical simulation are

  • 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.
