Abstract
In this article the heat flux distributions in idealized wind-aided flame spread are determined. The surface heat flux and the surface temperature can be found by numerically solving an integral equation. Algebraic expressions independent of the free stream velocity and the oxygen mass fraction are obtained for the surface heat fluxes. The ratio of total surface heat flux in the under-flame zone to that in the pre-flame zone is found as a function of the pyrolysis and flame-front speeds. In addition, the fractions of the total flame heat release that appear as heat fluxes to the pyrolysis region and to the preheating region are determined. An analytical expression is also obtained for the excess pyrolyzate.
