Abstract

An enclosed pool fire was simulated by injecting ethane through a 6.2 cm diameter porous plate. The diffusion flame was investigated at low, normal and high gravity to 12 g. From scaling relations based on Froude modelling, the experimental flame characteristics (height, fluctuation frequency and radiant fraction of the flame) were correlated. The results were used for validation of numerical models and scale analysis.
