Abstract
The Generalized Global Equivalence Ratio Model (GGERM) was developed to predict the generation rates of oxygen, fuel, and other products of combustion in rooms containing fires. The GGERM extends to general transient conditions the global equivalence ratio model established during times of steady-state in experimental studies involving two-layer compartment fires. The present work uses the GGERM to predict the time-dependent upper-layer mass fractions of products of combustion (fuel, oxygen, CO and others) in these and similar two-layer fire experiments. All predicted results are found to be plausible and, where transient data are available, predicted and measured results compare favorably.
