Abstract

A interactive, graphics postprocessor for numerical simulations of chemical kinetics (CHEMKIN) is described and examples of its utility is given for decomposition and oxidation chemistry for two systems: silicon hydrides and fluorinated hydrocarbons. This graphics postprocessor allows one to rapidly sort through and display species and reaction information generated in numerical simulations. Such interactive computations facilitate the development of a fundamental understanding of coupled chemically reacting systems by providing the ability to quickly probe the impact of process parameters and proposed mechanisms.

Example: Decomposition and Oxidation of Silicon Hydrides
