Abstract

Thermal transient characteristics of a unconfined ceiling jet, induced by a constant fire source, are modeled using the Favre-averaged, turbulent continuity and energy equations along with the equation of state. An empirical velocity profile is used as an input to the model whose results are the transient temperature profile of the ceiling jet. The numerical prediction are in good agreement with the experimental data. A Prandtl mixing length appear to work well for this approach.
