Abstract

In order to improve high-rise fire-extinguishing efficiency and reduce fire-extinguishing cost, a mathematical model of explosion and dispersion of extinguishing agent was built by using AUTODYN on the basis of isentropic expansion law of detonation outcome and theory of hydrodynamics to simulate the dispensing process of high-rise superfine powder fire-extinguishing agent. Different locations on the high-rise fire-extinguishing bomb were selected to be Gauss points and then were analyzed, all calculating results were contrasted finally. A method used for evaluating fire-extinguishing efficiency of fire-extinguishing bomb was put forward according to the analysis of agent concentration of different moment that it was dispensed, which was referentially meaningful to study the extinguishing efficiency of extinguishing agent.
