Development of a reduced kinetic mechanism for PICA pyrolysis products

Research output: Chapter in Book/Report/Conference proceeding › Conference contribution

Abstract

A Nonequilibrium Ablation and Pyrolysis model is presented along with the development of a detailed kinetic mechanism for the decomposition of pyrolysis products for carbon-phenolic thermal protection systems. The detailed mechanism consists of 49 species and 136 reactions. A simple procedure for kinetic mechanism reduction is outlined and then used to form a reduced model that is comprised of 19 species and 23 reactions. Results are obtained using the 19 species model for a 5 cm slab of PICA-like material heated to 1644 K. A more comprehensive and more fundamentally base mechanism reduction procedure is then employed to arrive at a reduced model which applies over the entire parameter space of the pyrolysis gas. The resulting reduced model consists of 19 species and 18 reactions. The benefits and problems associated with each mechanism reduction approach are also discussed.
