Summary

Mean flame height from the Heskestad correlation for three fire diameters; the dot marks the pallet stack example (2,600 kW, 1.21 m, 4.2 m). Based on Heskestad (2002), pp. 2-3 to 2-4.

Original vector illustration for Diffusion flame, level 2 Intermediate.

Source basis: Heskestad (2002), p. 2-3 (correlation, validity, negative heights unphysical) and p. 2-4 (pallet stack example)
Alt text: Line chart: mean flame height rising with heat release rate from 0 to 5,000 kW, for fire diameters 0.5 m, 1.21 m and 2.0 m.
