Chapman-Enskog and Burnett solutions for a simple, rigid-sphere gas: Numerical solutions using a subtraction technique

Chapman-Enskog and Burnett solutions are obtained for a simple, rigid-sphere gas through application of a subtraction technique to the linearized Boltzmann equation. The numerical results obtained converge and compare well with results reported previously using other techniques. This method is straightforward and may prove quite useful in addressing several other similar problems in the kinetic theory of gases.
