Abstract : This report describes a two-year investigation of smoke and toxic gas production in enclosed fires, particularly as applied to shipboard conditions. Quantification of smoke and toxic gas production, as a function of enclosure parameters such as fuelbed length scale and ventilation magnitude and geometry, are emphasized. A correlation of obscuration, as indicated by smoke opacity, with the instantaneous exhaust stream equivalence ratio was attempted. The results suggest a significant smoke production dependence on enclosure parameters. An analogous carbon monoxide production dependence is observed. Other observations involve smoke particle size and enclosure mass throughput. Upon ignition mass throughput usually decreases relative to non-burning conditions; however, in some cases of restricted ventilation settings, increases are observed. (Modified author abstract)
