On upward flame spread on thick fuels

Thomas, Philip and Karlsson, Björn (1990) In LUTVDG/TVBB--3058--SE 3058.
Abstract
Saito, Quintiere and Williams (1) developed an integral equation derived from quasi-steady thermal flame spread theory to describe spread up a thick solid. Allowance was made in this purely thermal model for a varying rate of pyrolysis and the relationship between flame length and burning rate was linearised. They discussed asymptotic solutions to their equation and derived the requirements for two-dimensional propagation both for a step function pyrolysis rate m" = constant up to a burnout time and an inverse square root variation. Here their integral equation is solved analytically by Laplace Transform and is also applied to pyrolysis which decreases exponentially with time.
