Abstract: Two multispeed discrete-velocity models have been used to study nearcontinuum compressible flow in an adiabatic channel. The first is a twodimensional, nine-velocity lattice gas in which particles jump between grid sites on a square lattice and collide with each other at those sites according to a specific set of collision rules. The model is implemented efficiently as a lattice gas automaton (LGA) in which particle movement and collisions are decoupled and both phases of the simulation can be computed with s…
