摘要:economic assets, and environmental resources in the United States and across the globe. One cause of the collapse of the World Trade Center and the collapse of the Deepwater Horizon drilling platform in the Gulf of Mexico was the failure of structural materials under large heat loads from fi res. Flame impingement or fl ame structure interaction studies are essential for understanding the effects of fi re on the structural integrity of buildings. Radiation is an important mode of heat transfer to the structural element, and measurements of radiation intensities from the fl ame are useful for improving the understanding of heat transfer from the fl ame to the structure. This study investigates the radiation intensities and radiation heat fl ux from fl ames with and without impingement on a fl at steel plate based on plate location relative to burner, fuel mass fl ow rate, and fuel type. The quantitative comparison between measured radiation intensities of impinging and non-impinging fl ames shows signifi cant increases in radiation intensities near the surface of the plate. The radiation heat fl ux to the environment is lower for impinging fl ames, indicating high heat transfer to the plate. Quantitative knowledge gained from this study can be used to estimate structural integrity under large heat loads and to manufacture structural elements that are more resistant to fi re
