Performance simulation of enclosure linings subject

to realistic regimes of fire exposure conditions

1997-2000, EPSRC GR/K89832/01

The overall objective of this collaborative project with the University of Ulster was to study the transition states and instabilities associated with ignition, flame spread, mass burning and product generation of enclosure linings in realistic fire conditions using numerical simulation and experimental measurement. The Cranfield component of this collaborative study focussed on the numerical simulation of the combustion of enclosure linings in real enclosure fire conditions, in parallel and integrated with the experimental programme at Ulster. The study employed spatially resolved CFD predictions of temperature and wall heat flux as input to phenomenological models describing lining ignition and subsequent combustion. Simulations of both full scale, end use, scenarios and the medium scale prototype rig developed by Ulster were accomplished.

Performance simulation of glazing systems exposed to room fires

1996-1999, EPSRC GR/K78454/01

The overall objective of this collaborative project with the University of Ulster was to investigate the mechanism of glazing system failure in room fires and to incorporate the results of detailed experimental measurement and numerical simulation in design guidelines. The Cranfield University sub-task was specifically the application of field modelling to the simulation of selected room fire configurations to provide spatially resolved CFD predictions of wall temperature and heat flux to establish detailed thermal boundary conditions for the performance evaluation of glazing systems. The simulations were evaluated by comparison with experimental data collected by the University of Ulster.
