Analytical Model of Pyrolysis for a Finite Thickness Sample on a Semi-Infinite Base (NISTIR 5904)

Abstract

To test the flammability of materials, a sample is placed on a substrate and exposed to a uniform heat flux. Measurements include sample mass and upper and lower surface temperatures as functions of time. Several analytical models have been developed in an attempt to fully understand the relationship between properties of the tested materials and test results. Most of these models have assumed a semi-infinite sample, although the finite thickness of the sample is known to have a significant effect on pyrolysis behavior. An analytical solution that includes finite sample thickness and the material properties of the base is introduced in this abstract.
