Impact of Water Mist on Heat Transfer and Chemical Species from a Liquid Pool Fire
Abstract
The present work provides an experimental and numerical study on suppression phenomena of a buoyant, turbulent heptane medium-scale pool fire via water mist. Detailed gas temperature is presented with and without the addition of a finely divided water mist (50μm). It is found that such mist has a combustion-supporting effect due to upward buoyancy-induced flow opposed to mist injection. The customarily described well defined structure of the flame does not exist any longer by application of water mist. This study evaluated the performance of two widely used fire simulation codes, such as Fire Dynamics Simulator and FireFOAM for predicting pool fire suppression via water mist thanks to the Large Eddy Simulation (LES) technique. The eddy dissipation concept (EDC) is applied to simulations of pool fire suppression, which considers one or three-step chemical reaction. Both simulation codes reasonably predicted the gas temperature trend, and FDS predicts lower temperature stratification in the thermal plume than FireFOAM after activating water mist.
