Abstract:

The large fires which follow nuclear detonations over a city present an important civil defense problem. The high temperature, high winds, high thermal radiation flux, and high noxious gas concentrations at street level present an adverse environment for the escape of people, for fighting fire, and for the operation of shelters. It is essential that civil defense planning be based on as reliable a knowledge of this environment as possible. Since the local conditions will be influenced by the entire mass fire, it is necessary to determine the characteristics of mass fires. The purpose of this research was to find out if the air velocities and temperatures that exist in the gross flow field above a mass fire could be determined from measurements made on a small scale laboratory-sized model of the mass fire, using electrical heating elements to provide the heat input.
