A Mathematical Model for Predicting Fire Spread in Wildland FuelsIntermountain Forest & Range Experiment Station, Forest Service, U.S. Department of Agriculture, 1972 - Flame spread - 40 pages A mathematical fire model for predicting rate of spread and intensity that is applicable to a wide range of wildland fuels and environment is presented. Methods of incorporating mixtures of fuel sizes are introduced by weighting input parameters by surface area. The input parameters do not require a prior knowledge of the burning characteristics of the fuel. |
