BURNETT EQUATIONS AND SHOCK STRUCTURE.

Abstract

The Chapman-Enskog expansion for the solution of the Boltzmann equation was re-examined and certain inconsistencies in the procedure were pointed out. For a steady state one-dimensional Boltzmann equation, the expansion is modified with the help of the PLK method. Macroscopic equations up to Burnett level of approximation are then obtained. Finally, these equations are used to examine the structure of a shock wave in a gas consisting of Maxwellian molecules. It is shown that new Burnett equations give solutions for all values of Mach number. (Author)
