WebThe equations presented by G. M. Byram in 1959 for calculating energy flow rate in the wind field (P w ) and in the convection column (P f ) above a wildland fire are inconsistent because units for each rate are not those of an energy rate (or power) per unit area.

WebFireline intensity is synonymous with the terms “Byram's fire intensity” (Byram 1959) and “frontal fire intensity.” It is the numerical product of a fire's rate of spread, fuel consumption, and heat yield at a given point on a fire’s perimeter. Reaction intensity and total fire flux are examples of other measures of fire intensity.
