Summary

The same heat release rate of 7.4 MW over a wide base (left) and a narrow base (right). The narrow fire has the higher dimensionless heat release rate and the taller flame. Based on Heskestad (2002), pp. 2-2–2-3.

Original illustration for Dimensionless heat release rate, level 4 Expert.

Source basis: Heskestad (2002), p. 2-2 (definition, Eq. 1) and p. 2-3 (flame height correlation, Eq. 2); heat release rate of 7,416 kW from Najafi et al. (2007), p. 2-27
Alt text: Two fires with the same heat release rate: a wide pan with a short flame and a narrow burner with a tall, slender flame.
