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.
