Guided Uncertainty Reduction Utilities (GURU) The GURU suite of tools is designed to enable informed collaboration between experimentalists and modelers specifically by providing feedback to enable measurement and model improvement:
Compute probability distributions for model parameters
Propagate this uncertainty through fire models in multiple scenarios and perform sensitivity analyses of model predictions
Compare model prediction probability distributions to validation data
Compute statistically informed model selection criteria
Develop requirements for data set quality and completeness
Develop minimum requirements for numerical pyrolysis models
Incorporate additional NIST Fire Research Division tools and Validation Data into the Material Flammability Database
Evolved Gas Analysis Tools
Average Molecular Weight [White paper on custom apparatus]
Gas Chromatography Mass Spectrometry (GC-MS)
Fourier Transform Infrared Spectroscopy (FTIR)
Characterization of the Condensed Phase
Gel Permeation Chromatography (molecular weight)
Organic Elemental Analysis (CHNS/O)
Expanded Model Validation The EFSP Project is focused on expanding the number of configurations and burning scenarios included in the experimental dataset provided for fire model validation. Special emphasis is made on developing new techniques to quantify and simulate the complex mechanisms at the interface between condensed- and gas-phase that control ignitability and material burning behavior (e.g., polymer melt flow, smoldering/glowing combustion).
