Zone Fire Model Jet: A Model for the Prediction of Detector Activation and Gas211 Temperature in the Presence of a Smoke Layer

摘要

The zone model JET is a two-zone, single compartment computer model designed to211u001epredict the plume centerline temperature, the ceiling jet temperature and the 211u001eceiling jet velocity produced by a single fire plume. The impact on the upper 211u001elayer due to the presence of draft curtains, ceiling vents and thermal losses to 211u001ethe ceiling are included in the model. Ceiling mounted fusible links and link 211u001eactuated ceiling vents can be included in the model calculations. The unique 211u001efeature of this model is that the characteristics of the ceiling jet depend of 211u001ethe hot layer.
