Abstract:
The International Fire Sprinkler, Smoke & Heat Vent,
Draft Curtain Fire Test Project organized by the
National Fire Protection Research Foundation (NFPRF)
brought together a group of industrial sponsors to
support and plan a series of large scale tests to study
the interaction of sprinklers, roof vents and draft
curtains of the type found in large warehouses,
manufacturing facilities, and warehouse-like retail
stores. In conjunction with the large scale tests, NIST
developed a numerical model based on large eddy
simulation techniques, the Industrial Fire Simulator
(IFS), that could be used to plan, analyze and
supplement the test results. A series of bench scale
experiments was conducted to develop necessary input
data for the model. These experiments generated data
describing the burning rate and flame spread behavior of
the cartoned plastic commodity, thermal response
parameters and spray pattern of the sprinkler, and the
effect of the water spray on the burning commodity.
