Prediction of Incident Heat Flux of Facade Considering Opening Jet Plume

Abstract

In this study, a combustion experiment was performed by setting fire source conditions to generate an opening fire plume and flame for various opening shapes using a large-scale compartment model. It was confirmed that the opening temperature and incident heat flux increased with increasing fire source condition. Regression analysis was performed using the relationship between the dimensionless number <math xmlns="http://www.w3.org/1998/Math/MathML"><msubsup><mi>Q</mi><mi>D</mi><mrow><mo>*</mo><mo>-</mo><mn>2</mn><mo>/</mo><msub><mn>3</mn><mrow><msup><mi>Z</mi><mo>*</mo></msup></mrow></msub></mrow></msubsup></math> and the incident heat flux <i>q</i>″. Comparison of the derived formula with the experimental value confirmed the validity of the results.
