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.
This research was undertaken while Dr. Peter Cumber was on a research visit to the Department of Civil Engineering, University of Canterbury, Christchurch, New Zealand. He would like to thank the Royal Academy of Engineering for the Global Research Award and the EPSRC for the Overseas Travel Grant, GR/T22735 that made this secondment possible.
