Abstract : This research resulted in the development of a computer model for prediction of Horizontal Flame Spread on Compartment Surfaces (HFSCS) complemented by a Combustion Model. The HFSCS was developed to predict flame spread on real material (whose properties are not always known or well-defined). The intent of the work was to provide the Navy with a validated and practical numerical model that can be used either as an stand alone for material flame spread characterization or ideally be incorporated into a compartment fire model such as C-FAST developed by NIST. The horizontal flame spread code has been assembled including burning and radiation from the spreading fire. The numerical model was validated by comparison predicted flame spread rates and surface temperatures with measurements from several experiments which included effects of external and flame radiative heat fluxes. Good agreements between the numerical predictions and the experimental data were obtained. The theoretical details of the models, subroutines and analysis are contained in Appendixes A-F. The computer code for the HFSCS and the combustion model are provided on magnetic disk. A listing of the HFSCS and the combustion model along with their input and description of the input are included in Appendix (G-J). Extensive presentation of the data and results are included in the Appendixes L and M.
