The capability of the Lattice Boltzmann method to simulate rarefied gas
flows for which the Knudsen-number is the characteristic dimensionless
number is investigated. Recently developed modifications to the Lattice
Boltzmann method enable it to solve the described problem, which is
illustrated with several test cases. To simulate the diffuse spreading of
a second component in the described flows a hybrid approach is proposed
and tested combining the Lattice Boltzmann method with simplified
Molecular Dynamics simulations.
