文摘The Broadwell model is the simplest spatial model of the Boltzmann equation. The exact travelling wave solutions of the Broadwell model are studied in a concise way with proof of their existence and uniqueness of form. The results ameliorate the conclusions of previous investigator. The results suggest a general method for obtaining nontrivial exact solutions for the similar discrete Boltzmann equation.
