- zone model JET evolved from the computational platform used for the zone model LAVENT and therefore contains many of the features found in LAVENT; JET is a two-zone, single compartment model where each zone or layer is assumed to be uniform in density and temperature
- Abstract
- 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.
