The zone model JET is a two-zone, single compartment
computer model designed to predict the plume centerline
temperature, the ceiling jet temperature and the ceiling
jet velocity produced by a single fire plume. The impact
on the upper layer due to the presence of draft
curtains, ceiling vents and thermal losses to the
ceiling are included in the model. Ceiling mounted
fusible links and link actuated ceiling vents can be
included in the model calculations. The unique feature
of this model is that the characteristics of the ceiling
jet depend on the depth of the hot layer.
