Flame extension area of unconfined thermal ceiling jets induced by rectangular-source jet fire impingement

Flame extension area is a significant parameter of thermal ceiling jet, which directly determines the strong heat transfer area between the thermal plume and the building ceiling. Experiment was conducted to investigate the flame extension area induced by rectangular source fires in this work. Results show that the flame extension area data sets can not be precisely predicted by former correlations. The aspect ratio of rectangular fire source...
