Abstract

The burning rate of a hot graphite rod placed in an uniform stream of cold oxidizer has been investigated numerically and comparisons have been made with existing experimental data. The model has employed a detailed reaction mechanism for the homogeneous reactions and a semi-global mechanism for the heterogeneous reactions. Burning rate predictions as a function of the surface temperature are presented for various oxidizer conditions (moist air, moist oxygen and pure carbon dioxide), strain rates and graphite densities. While the present results indicate the importance of C2 + O → CO reaction and the surface area effects in determining the semi-global rate data, reasonable comparisons with previous theoretical analyses give added validity to the basic understanding of the carbon oxidation mechanisms described in previous studies.
