- Abstract
- This report discusses a portion of the research completed under NBS Grant No. 5-9020, during the period July 1, 1975 to December 31, 1975. The investigation considers the properties of a burbulent fire burning on a vertical surface, under natural convection conditions. Both the pyrolysis zone (where the wall material decomposes to provide gaseous fuel for the fire) and the plume region (where combustion is completed and the thermal plume above the fire decays by mixing with the ambient gas and by heat transfer to the nonburning protions of the surface) were considered. Burning rates were measured in tye pyrolysis zone; radiative and convective heat fluxes to the surface were measured in the plume region; and profiles of mean velocities and temperatures were measured in both regions. Simplified integral models are developed to provide a convenient basis for correlating and interpreting the measurements.
