Abstract

A series of fire tests were conducted in a full-scale open corner with a ceiling to measure the thermal field generated by fires located in a corner. Fires were produced using different size (0.17, 0.30, and 0.50 m) square and line propane burners with heat release rates ranging from 25 to 300 kW. Burner distance below the ceiling was also considered. Measurements included flame length, gas temperatures, and total incident heat flux onto the noncombustible corner boundaries. Flame lengths were related to Q*, with the burner dimension as the length scale, and were found to be similar to those measured in studies with no ceiling. By dividing the corner into three regions (corner walls (z/Hz/H greater than 0.8), and ceiling, empirical relations for estimating the gas temperatures and incident heat fluxes were developed. Incident heat fluxes on the corner walls were measured to be similar to those in other studies.
