Fire behavior in chaparral-Evaluating flame models with laboratory data

摘要

Flame and mass loss data for chaparral, a mixture of shrub plants from the Mediterranean climate zone of southwestern North America, from five previously reported experiments were used to evaluate several published models relating flame characteristics to mass loss and heat release rates. These data are unique with fuel moisture content ranging from 0.36 to 0.94 (dry basis); the study used mass loss rates which included water loss. Fit of the data to Froude number correlations developed by Albini, Byram, Nelson and Thomas and heat release rate flame length correlations by Heskestad, Zukoski, and Yuan/Cox for axisymmetric and line fires were examined.
