12. Improved Understanding of Thermal Agent Fire Suppression Mechanisms from Detailed Chemical Kinetic Modeling with Idealized Surrogate Agents
Published: 8/4/2008
Author: William M Pitts
Abstract: Fire suppression agents that derive their entire effectiveness from physical processes are known as thermal agents. Thermal agents operate by lowering the flame temperature through dilution, heat absorption, and thermal diffusion. Two aspects of thes ...
