On Correlating Mixed Forest Fuel Bed Fire Spread Data
Jiann C. Yang
Mixing rules are proposed and used to correlate well-mixed forest fuel bed fire spread data from the literature using the dimensionless correlations previously developed for single-species forest fuel bed fire spread with the help of dimensional analysis and the resulting dimensionless groups. The mixing rules provide means to treat well-mixed fuels as pseudo single-species fuels. As a first attempt with very limited experimental data, the dimensionless correlations for single-species fuels may be applicable to mixed-species fuels with proper mixing rules.
