Modeling of One-Dimensional Smoldering of Polyurethane in Microgravity Conditions
(The Combustion Institute, 2004-08)
Results are presented from a model of forward smoldering combustion of polyurethane foam in microgravity. The transient one-dimensional numerical-model is based on that developed at the University of Texas at Austin. The ...
Application of Genetic Algorithms and Thermogravimetry to Determine the Kinetics of Polyurethane Foam in Smoldering Combustion
(Combustion and Flame, 2006-04)
In this work, the kinetic parameters governing the thermal and oxidative degradation of flexible polyurethane foam are determined using thermogravimetric data and a genetic algorithm. These kinetic parameters are needed ...
Computational Model of Forward and Opposed Smoldering Combustion in Microgravity
(The Combustion Institute, 2006-08-06)
A novel computational model of smoldering combustion capable of predicting both forward and opposed propagation is developed. This is accomplished by considering the one-dimensional, transient, governing equations for ...
The role of secondary char oxidation in the transition from smoldering to flaming
(The Combustion Institute, 2006-08)
The transition from forward smoldering to flaming in polyurethane foam is observed using indepth thermocouples and ultrasound probing. The experiments are conducted with small parallelepiped samples vertically placed in ...
Modelling the Propagation of Forward and Opposed Smouldering Combustion
A computational study has been carried out to investigate smouldering ignition and propagation in polyurethane foam. The one-dimensional, transient, governing equations for smouldering combustion in a porous fuel are ...
