A study of flame spread in engineered cardboard fuelbeds: Part II: Scaling law approach


Adam, Brittany A.; Akafuah, Nelson K.; Finney, Mark; Forthofer, Jason; Saito, Kozo. 2013. A study of flame spread in engineered cardboard fuelbeds: Part II: Scaling law approach. In: Seventh International Symposium on Scale Modeling (ISSM-7); Hirosaki, Japan; 6-9 August, 2013. International Scale Modeling Committee. 10 p.

In this second part of a two part exploration of dynamic behavior observed in wildland fires, time scales differentiating convective and radiative heat transfer is further explored. Scaling laws for the two different types of heat transfer considered: Radiation-driven fire spread, and convection-driven fire spread, which can both occur during wildland fires. A new interpretation of the inertial forces introduced a downstream, time-dependent frequency, which captures the dynamic, vortex shedding behavior of flames due to the unstable nature of the turbulent flow created in the wake of the fire. Excelsior and paper strip experiments suggest wildland fire is a falls into the convection-driven spread regime.
