- Abstract
- This study involves the development of a computer code to predict the power density (rate of heat generation per unit land area) produced by building fires caused by a nuclear attack on an urban area and its application to typical areas of San Jose and Albuquerque for various attack conditions. A scheme was also developed to rapidly estimate the power density by hand calculaiton. In addition to predicting the power density, the code predicts the radiant intensities in the streets from the burning buildings and the radiant heating of the air. Also, studies were conducted to ascertain the effects of the thermal environment on personnel in the streets and related to the effects of fallout. Permissible exposure times are indicated for the two effects.
