Table 1 Characteristics of fires and resulting plume-model boundary conditions used to predict xylem cavitation. Fuel consumption was held constant at 0.75 kg m−2 while wind speed (W) and flame rate of spread (R) varied, creating a range of fireline intensites (I). Flame height (h f ) is determined by wind speed and fireline intensity while initial plume velocity (w i ) is dependent on fireline intensity and initial plume half width (b i ) is dependent on flame width.
