高温气体反应流中的物理力学问题

SOME ASPECTS OF HIGH TEMPERATURE REACTING GAS FLOW IN PHYSICAL MECHANICS

从气体动理论(kinetic theory of gases)的原理出发导出了非平衡条件下高温气体反应流基本守恒方程组.讨论了出现在方程组中的各种通量在非平衡条件下的意义,给出了从微观出发的输运系数表达式.介绍各种物理动理论与化学动理论过程的微观理论,讨论了在非平衡条件下现有理论的困难.

The basic conservation equations for noncquilibrium high temperature reacting flow arc derived from the gas kinetic theory. In the nonequilibrium region, the meaning of the fluxes contained in these equations is discussed. The expressions of the transport coefficients based on a microscopic approach are given. The microscopic theories of some physical and chemical kinetic processes arc described, and the difficulties of thcsc theories in the nonequilibrium region are discussed.
