A STUDY OF OXIDATION PRODUCT CO/CO_2 ON THE CARBON/CHAR SURFACE

本文通过严格的求解一组包括空间反应在内的微分方程,并辅以准确的碳粒燃烧速率及其温度的实验测定,得到了计算碳/炭粒表面氧化反应生成物C0/CO_2比值的通用表达式,它较之前人的经验公式更准确、通用。从而为碳/炭粒的温升历程及其着火温度的预报提供了可靠的理论基础。

A expression for calculation CO/CO2 of the oxidation reaction on the carbon/char surface is presented in this paper. Based on strickly solving a set of differential equations in eluding the reaction in the space, in which the accurate burning rate and the temperature of the carbon particle must be experimentally measured. The expression for calculating CO/CO2 given the paper is more accurate and general than previous ones. Thus a reliable theory is provided for predicting temperature histories and ignition temperatures of the carbon/char particles.
