Wang Mechanism Results

This study examines the chemical basis for simplified chemical reaction models. As a part of this study, we have examined the question of the existence of a temperature cutoff which has been proposed as the basis for formulating previous 3-step models. More details about this study are given in our 2005 Combustion Institute Sectional paper. Below are results of constant volume explosion simulations for acetylene, ethylene, and propane using a mechanism developed by Hai Wang.
