This transient phenomenon is an example of typical catastrophe behaviour. In this paper, a simplified mathematical model of backdraft in In other words, Fire Dynamics is the study of how fires start, spread and develop. Fifteen years ago tomorrow, three members of the Fire Department of the City of New York (FDNY) lost their lives while conducting search in a three story apartment building located at 62 Watts Street in Manhattan.

Backdraft is a fire phenomenon in which the hot gasses formed from combustion at low oxygen levels rapidly combust due to abruptly supplying abundant fresh air. But what exactly is a fire? Fire Dynamics is the study of how chemistry, fire science, material science and the mechanical engineering disciplines of fluid mechanics and heat transfer interact to influence fire behavior. If you have any additional questions please contact Sean Gray and P.J. The backdraft is one of those conditions that if not prepared for can lead to a drastic injury or even loss of life. Backdraft at 62 Watts Street. A backdraft is a rapid or explosive burning of superheated gasses in a fire, caused when oxygen rapidly enters an oxygen-depleted environment; for example, when a window or door to an enclosed space is opened or broken.
