Title: TREATMENT OF FIRE SOURCE IN CFD MODELS IN PERFORMANCE BASED FIRE DESIGN

Traditionally, instead of complex combustion model, the fire source was just taken as a volumetric heat source with prescribed heat release rate in practical fire simulation. However, it was always argued about the accuracy of CFD results with such simplification. This paper presents the comparison of simulation results of fire field models with volumetric heat source method and submodels of combustion model and radiation model, altogether with the available experimental data under different fire scenarios. Some guidance and discussion of important issues related to the application of fire field modeling on performancebased fire design, which needed special consideration and proper practical application, were provided in this paper.Read More
