Title: A note on flame length and upward flame spread

Ref Code: FN6
Authors: P H Thomas

Abstract1: Recent engineering applications of theories of upward flame spread have used empirical data to describe the connection between the gas and solid phases. At its simplest this approach requires a mean net heat flux to be given over the length of the flame ahead of the pyrolysing zone. Over this distance an output of heat release per unit area is specified. This Fire Note comments on the difference between a linear law and the more conventional 2/3 power law. It explores some variations in the simple thermal model of upward flame spread, and uses it to examine the role of sideways spread.
