- Abstract
- This is a progress report of an applied model validation case study. The subject model is "Transport of Fire, Smoke and Toxic Gases (FAST)" by W.W. Jones of the National Bureau of Standards, Center for Fire Research. Products from a fire in a "burn room" exit through a connected corridor to outdoors. Cooler counterflow air in a lower layer feeds the fire. The model predicts corridor layer temperatures and thicknessess vs. time, given enclosure, fire and ambient specifications. Data have been collected from 38 tests using several fire sizes. Corresponding model results, and model and test documentation are yet to come. Considerable modeling and calculation is needed to convert instrument readings to test results comparable with model outputs so that residual differences may be determined. Test results as well as model results must be validated, and test result uncertainties estimated so that they are not unfairly attributed to the model.
