Catastrophe analysis of the water mist fire suppression process

  • Received Date: 15 Feb 2012

  • To understand the water mist fire suppression mechanism and find out the extinguishment boundary, the water mist fire suppression process was analyzed with a non-linear catastrophe theory. The expressions of the flame energy potential function and the flame critical extinguishing temperature were deduced. The extinguishment criterion for the n-heptane pool fire was obtained. The extinguishment boundary is verified by conducting the water mist fire suppression experiments on n-heptane pool fire. The effect of oxygen concentration on the flame extinguishing temperature is quicker than that of heat absorption.
