Laboratory Fire Modeling. 1. Wind-Aided Flame Spread. 2. Wet Coagulation of Smoke

摘要

Design, construction, instrumentation, and preliminary utilization have been carried out for two laboratory-scale apparati concerned with specific incendiary effects in a thermonuclear aftermath. One apparatus is a fire tunnel dedicated to wind-aided fire propagation across a regular two-dimensional array of discrete polymeric fuel elements (specifically, toothpicks). This work is dedicated to quantifying a local incendiary effect, the rate of fire spread across strewn debris in the presence of an ambient wind. Preliminary findings suggest that the rate of spread increases directly as the square root of the wind speed and inversely as the square root of the fuel loading, for conditions for which spread occurs at all.
