AN ATTEMPT to simulate shock waves using the Boltzmann
equation (BE) has been made by Mott-Smith [1] who proposed
a bimodal distribution function consisting of two Maxwellian terms
to describe molecular collision behavior in the BE.The solution was
then compared with an approximate solution of the BE for strong
shocks where the Chapman–Enskog [2] expansion method was used
to recover the Navier–Stokes (NS) equations.This approach proved
to be satisfactory for the simulation of the structure of strong shocks
but was not valid for shocks with low to moderate Mach numbersM.
Extension of the Mott-Smith approach to low to moderate M was
attempted by Salwen et al.[3].Since then,attempts to model the BE
have been made by various researchers; among them,a commonly
accepted model was that due to Bhatnagar et al.[4],hereafter
designated as the BGK model.The model was proposed for
monatomic gas only and considered the deviation of the particle
distribution function f from its equilibrium state feq to be small.
Thus,the nonlinear character of molecular collision was modeled in
feq,which BGK assumed to be described by a Maxwellian
distribution.The lattice Boltzmann method (LBM) devised from this
model found success in the simulation of incompressible,isothermal
flow,where the equation of state for monatomic gas is automatically
satisfied.Its extension to simulate compressible air flows,even with
low Mach number (M
