The radiative-convective partitioning of heat transfer to objects in large pool fires

This paper explores the relative contributions of radiative and convective heat transfer to objects in large pool fires. The partitioning process depends on many factors. Results include measurements of the temperature of the objects in the fire, the flames surrounding the object, the total heat flux to the objects and the radiative component of the heat transfer at a few locations using transpiration radiometers. These measurements will be compared with calculations. Agreement between the measured radiative heat flux and the calculated radiative heat flux is good. The convective contribution was calculated from the total and radiative parts and was found to be from 10--20% of the total. 18 refs., 18 figs.
