Dimensional Analysis on Forest Fuel Bed Fire Spread

Published

Author(s)

Jiann C. Yang

Abstract

A dimensional analysis was performed to correlate the fuel bed fire spread data previously reported in the literature. Under wind condition, six pertinent dimensionless groups were identified, namely dimensionless fire spread rate, dimensionless fuel particle size, fuel moisture content, dimensionless fuel bed depth or dimensionless fuel loading density, dimensionless wind speed, and angle of inclination of fuel bed. Under no-wind condition, six similar dimensionless groups less dimensionless wind speed resulted. Given the uncertainties associated with some of the parameters used to estimate the dimensionless groups, the dimensionless correlations using the resulting dimensionless groups correlate the fire spread rates reasonably well under wind and no-wind conditions.
