Lattice Gas Simulations

All the lattice gas models have been used to simulate many different flow situations. These include single fluid simulation such as Poiseuille flow in a pipe [31]; Von Karman street formation behind a flat plate [32, 33, 19]; flow over a step [34]; vortex shedding behind various objects inserted in a steady flow [35]; jet simulation [35]; injected flow from a pipe into a transverse flow [36] and multiple fluid simulations such as the Kelvin-Helmholtz instability [25].

• Drawbacks of the Lattice Gas Approach
  • Lack of Galilean Invariance
  • Noisy Results
  • Large Collision Matrices
  • Non-Physical Phase Separation
