Characterization of heat transfer to calorimeters engulfed in pool fires is extremely important. To estimate the heat flux to the calorimeters, experiments are performed with horizontal stainless steel 304L pipes engulfed in diesel pool fires. The concept of adiabatic surface temperature is applied to predict the incident heat flux to horizontally oriented calorimeters engulfed in diesel pool fires. Plate thermometers are used to measure the adiabatic surface temperature for diesel pool fires. The estimated subsurface temperatures inside the steel pipes using the adiabatic surface temperature concept and the measured temperatures are in good agreement. Adiabatic surface temperature is also computed from fire simulations. The incident heat fluxes to the steel pipes engulfed in fire predicted from the simulations are found to be in good agreement with the experiments. The fire numerical code is validated against the 1 m pool fire experimental results of centerline temperature distribution and irradiances away from fire. A correlation is provided for the estimation of adiabatic surface temperature for large diesel pool fires. These results would provide an effective way for thermal test simulations.

Computational heat transfer became one of the major tools for engineering system design in 1970’s. It has been introduced into Chinese society since 1980’s, especially after Brian Spalding’s first lecture in 1984 in China. As one of Brian’s a few early visiting scholars from China, Professor W. C. Fan has begun his endeavor to expand computational heat transfer to fire research. This paper will first briefly introduce the history of the development of computational modeling with particular applications in fire research — a state funded large project, and then present some representative research work in fire research including recent works on high altitude fire and performance based design.
