Evaluation of the HDR Fire Test Data and Accompanying Computational Activitieswith Conclusion from Present Code Capabilities. Volume 2. CFAST Validation for T51 Gas Fire Test Series

摘要

This report addresses the following aspects of CFAST validation: Section 1briefly describes the rationale for selecting the four different experiments from the total of 11 HDR gas burner experiments in the HDR containment. Section 2 documents in great detail the individual aspects of input data addressing: environment and runtime control, combustion model, and surface properties which are generic different CFAST models developed for comparison with the 4 HDR experiments. Section 3 provides detailed comparisons between data and CFAST model predictions for the CFAST models described in Section 2. Section 4 addresses all of the accomplishments achieved with CFAST during this project phase, as well as various findings and issues regarding the model setup and application of CFAST. Complete input files for all CFAST computations documented in this report are presented in the Appendix A.
