Abstract
Abstract
A mathematical model is being developed to describe the pyrolysis (degradation of solid materials exposed to external heat) and heat release rate of aircraft cabin materials in the OSU (Ohio State University) apparatus. The OSU apparatus is used to expose aircraft interior cabin materials to an incident radiant heat flux of 35 kW/m2. This test determines if the material complies with FAR 25.853 requirements. The OSU heat release rate apparatus is a Federal Aviation Administration (FAA) designated combustion test instrument for testing the heat release rate of aircraft cabin materials. The results of the research completed include transient solutions of the flow-field variables (velocity, temperature, and pressure) within the fluid domain of the OSU apparatus using ANSYS FLUENT. A model of the basic overall geometry with a surface-to-surface radiation model was also developed. For the ongoing pyrolysis simulations of the specimens, a reduced computational domain has been considered that will include the effect of the radiant heaters (along a boundary of the proposed domain (Figure 6), the specimen holder within the OSU apparatus bounding walls.
