摘要: This paper continues the author's study of procedures for rewriting well-known Chapman–Enskog expansion used in kinetic theory gases. The usual expansion, when isothermal fluid motion, will introduce nonlinear instability at super-Burnett order O(e3) truncation. procedure given here eliminates truncation and produces desired dissipation inequality.
