Abstract

A thermally thick slab of polymethyl methacrylate was used to study the effects of the inclination of a fuel surface on upward flame spread. While investigation of upward flame spread over solid fuels has typically been restricted to an upright configuration, inclination of the fuel surface from the vertical is a common configuration that has not yet been adequately addressed. By performing experiments on a 10 cm wide by 20 cm tall polymethyl methacrylate fuel it has been found that the maximum flame spread rate, occurring in a vertical configuration, does not correspond with the maximum fuel mass-loss rate, occurring closer to a horizontal configuration. A detailed study of both flame spread and steady burning on this fuel surface along angles of inclination has revealed the influence of buoyancy-induced flows modifying the heat flux profile ahead of the flame front, which controls flame spread, and the influence of the heat flux to the surface of the fuel, which controls fuel mass-loss rates.
