The National Fire Protection Association has recognized fast-response sprinkler technology, developed and promulgated by Factory Mutual Research Corporation (FMRC, now FM Global), with its 2019 Phillip J. DiNenno Prize. This technology was the result

Practically all fires go through an important, initial stage in which a coherent, buoyant gas stream rises above a localized volume undergoing combustion into surrounding space of essentially uncontaminated air. This stage begins at ignition, continu

Responding to a challenge raised with respect to a 1989 revision of a 1979 paper on the ceiling jet of t-squared fires, we have measured the heat of combustion in the growth phase of wood cribs made of sugar pine, the test fuel in the original work,

This paper describes a reduced-scale study of the contamination field (“smoke”) arising from a fire source in a space where air normally flows vertically at uniform velocity in a near-laminar state from ceiling to floor, as in many industrial cle

Extinction in open space of flames from pool fires by downwardly directed water sprays has been investigated on two linear scales, one three times larger than the other. Circular pool fires were employed as fire sources, mostly in the form of gas dis

Scaling relations for (dry) compartment fires have been extended to include interactions of water sprays with the gas phase, including flames. All important interactions scale properly, except attenuation of thermal radiation by the sprays. Methods o

Recent measurements of rise times of plumes from suddenly initiated steady fires versus observation height have been expressed as a constant dimensionless rise time. Rise times deduced from the literature for t-squared, power-law fire growth have als

Literature data on flame heights of turbulent jet diffusion flames are examined in ratios to flame heights of purely buoyant turbulent diffusion flames. The flame height ratio is found to be a function of the gas release momentum in ratio to the mome

Scaling relations for the initial convective environment generated by power-law fires in geometrically similar spaces are derived, comprising functional relations for nondimensional temperature rise and gas velocity as functions of nondimensional tim
