Heat transfer to large objects in large pool fires

Abstract A series of large pool fires has provided temperature and heat flux data for a large, thermally massive object. Tower temperatures were obtained at 4 elevations. Temperature measurements on a large calorimeter were used to obtain heat flux levels at 3 axial stations and 4 angular locations. The tests show large spatial and temporal variations for each test that seem to be largely driven by wind effects. A conditioning analysis was used to extract data at periods of lower wind velocities to allow a comparison between test data and simplified fire models. The conditioned data shows a significantly lower variance and better symmetry around the large calorimeter.
