CFD MODELLING OF FIRE SUPPRESSION BY WATER SPRAY:SENSITIVITY AND VALIDATION FOR A POOL FIRE IN A ROOM

摘要

In 1998, MoD commissioned ANSYS CFX torndevelop a numerical procedure, based onrnComputational Fluid Dynamics (CFD), aimed atrnproviding a practical tool which can be integratedrninto design processes in order to optimise lowpressurernfine water spray fire suppression systems.rnThe work, which employs the CFX software,rnincluded a sensitivity study which investigated therninfluence of a number of parameters and comparedrnthe predictions with an experiment conducted by thernLoss Prevention Council (LPC). This paper outlinesrnparts of that work. Preliminary results werernencouraging. The work has progressed to a secondrnphase, which will include large-scale validation.
