This report discusses research completed under NBS Grant No. 7-9020, during the period September 1, 1977 to August 31, 1978. The investigation considers the processes which occur when a turbulent fire impinges upon a horizontal ceiling. Measurements were conducted to determine free flame heights, impinging flame lengths along the ceiling, ceiling heat fluxes and mean temperature distributions in the flow. Both unconfined and confined ceilings were considered. Theoretical analysis was completed in order to suggest simple methods for correlating the data.
