A platform for research: civil engineering, architecture and urbanism
The results of summer studies by four professors on the scaling of mass fires and the burning rates of materials in large fires are presented as appendices of this report. These results are summarized and analyzed in terms of their application to the civil defense mass fire problem. Overall mass fire scaling alone cannot determine the street environment which is required for civil defense planning. This information may, however, be obtainable from overall mass fire scaling in conjunction with local mass fire scaling and some flame interaction experiments. The mass fire scaling schemes discussed fall into three categories: (1) the surface heat flux or surface temperature is specified. (2) The rate of fuel gas evaluation at the surface instead of the heat flux or temperature is specified. (3) The Reynolds number and the Grashof number along with two radiation parameters, a fuel gasification parameter, and a gas phase heat release parameter are held fixed by operating the model with a modified atmospheric composition and gravitational acceleration constant using a pressure chamber and a centrifuge.
