Abstract:

The purpose of this volume is to provide a means for quantitative comparison of model simulations and measurements. The methodology employed follows the guidelines outlined in ASTM E 1355, Standard Guide for Evaluating the Predictive Capability of Deterministic Fire Models, for verification and validation (V&V) of the selected fire models. That guide outlines four parts of model evaluation: 1. Define the model and scenarios for which the evaluation is to be conducted. 2. Assess the appropriateness of the theoretical basis and assumptions used in the model. 3. Assess the mathematical and numerical robustness of the model. 4. Validate a model by quantifying the accuracy of the model results in predicting the course of events for specific fire scenarios. This volume describes the methodology used to addresses the fourth part of the ASTM model evaluation process. The other parts are found in Volumes 1 and 3 through 7 of this report series.
