Summary

Typical and measured flame spread rates. Spread with the flame lying along the fuel is faster, and on long floor-mounted samples under forced flow it reached 1 to 6 cm/s. Based on Quintiere (2002b), pp. 2-247 and 2-253.

Original illustration for Trench effect, level 4 Expert.

Source basis: Quintiere (2002b), p. 2-247 (Table 2-12.1) and p. 2-253
Alt text: Log-scale range bars: lateral or downward near 0.1 cm/s, short samples 0.01 to 0.3, long floor samples 1 to 6, upward spread 1 to 100 cm/s.
