Abstract

This paper provides an overview of selected measurements from a series of 90 full-scale fire experiments quantifying the impact of material composition on full-scale burning and fire growth behavior. Samples were selected to provide a wide range of material compositions (i.e., chemistries) and burning behaviors: physical deformation (e.g., swelling, charring collapse, dripping, and/or melt flow), heavy or light soot formation, and varied ignitability and fire growth rates. In total, 18 unique combustible solids were tested including: natural and synthetic polymers, copolymers, fiberglass-reinforced composite materials, porous polymer foams, and electrical cables. Collectively, these experiments offer a comprehensive set of validation data for computational fluid dynamics (CFD) simulations of large scale fire growth due to flame spread over the surface of combustible solids. Here, a subset of these measurements is highlighted: flame heat flux, structure, and heat transfer mechanism.
