Modeling Lifted Methane Jet Fires Using the Boundary-Layer Equations

ABSTRACT The focus of this article is turbulent lifted jet fires. The main objective is to present a lifted jet fire methodology using the boundary-layer equations as a basis. The advantages of this are that finite-volume, mesh-independent predictions of the mean flow fields can be calculated on readily available computer resources, which leads to rigorous model calibration. A number of lift-off models are evaluated. The model of choice is one based on the laminar flamelet quenching concept combined with a model for the large-scale strain rate.
