Fundament/j. Processes of Ignition and Combustion Relating to Fires Caused by Nuclear Detonations

The fundamental processea of ignition and eonbuation are reviewed to date as part of the OCD program for aaseaaing urban vulnerability to fire from nuclear barste* Sufficient background infomatlon is provided for use in future fire-damage aaaesaments and fire-protection procedures. Included are definitlona of the types of ignition and combustion, the factors governing ignition and combustion, and the mechanisms by which fire propagates. The technical material presented serves as background information for determining the importance of each of the parameters governing ignition and combustion, the synergistic effects of luteracting parameters, and what additional information is needed on the governing parameters and their interrelatiore. -
