THE MODELING OF FIRE GROWTH AND FIRE SUPPRESSION WITH HELP OF INERT GASES WITH SUBSEQUENT RECIRCULATION

Abstract

The model of fire growth and fire extinguishment in channels with the help of inert gases with subsequent recycling was designed. Gas compression in high temperatures outside the fire bed not taken into account by previous researchers, was taken into consideration in present research. Numerical modeling of fire extinguishment with the help of inert gases within some time without recirculation and with subsequent recycling was completed. The pictorial demonstration of modeling results provides a complete picture of the effectiveness of fire-extinguishing with help of inert gases and helps estimate the time needed to extinguish the fire.
