Summary: "Large outdoor fires are increasingly frequent, as climate and weather patterns change. The exceptionally high costs of recent forest and wildland-urban interface fires have drawn international attention. This systematic overview sets out useful engineering equations and computational models for analysing large outdoor fire dynamics, and presents practical approaches to risk assessment. It details the broad range of items needed for analysing risks and for designing plans to improve resilience in the built environment. This book shows professional engineers and researchers how to use or develop analytical tools, and also serves graduate courses"-- Provided by publisher

Description
Large Outdoor Fire Dynamics provides the essential knowledge for the hazard evaluation of large outdoor fires, including wildland, WUI (wildland-urban interface), and urban fires. The spread of outdoor fires can be viewed as a successive occurrence of physical and chemical processes - solid fuel combustion, heat transfer to surrounding combustibles, and ignition of heated combustibles - which are explained herein. Engineering equations frequently used in practical hazard analyses are derived and then integrated to implement a computational code predicting fire spread among discretely distributed combustibles. This code facilitates learning the procedure of hazard evaluation for large outdoor fires.
Chapters cover underlying assumptions for analyzing fire spread behavior in large outdoor fires, namely, wind conditions near the ground surface and fundamentals of heat transfer; the physical mechanism of fire spread in and between combustibles, specifically focusing on fire plumes (both reacting and non-reacting) and firebrand dispersal; and the spatial modeling of 3D objects and developing the computational framework for predicting fire spread.
The book is ideal for engineers, researchers, and graduate students in fire safety as well as mechanical engineering, civil engineering, disaster management, safety engineering, and planning. Companion source codes are available online.
