Abstract : Validation of fire models using large scale fire tests is important in the development of dependable and accurate fire models. Validation is especially critical as new phenomena are added to fire models. This report compares predictions from the Consolidated Fire Growth and Smoke Transport (CFAST) fire model to data from real scale fire tests conducted onboard ex-USS SHADWELL, the Navy's R&D Damage Control Platform. The phenomenon of particular interest in this validation is the conduction of heat in the vertical direction, which was recently added to CFAST in the ongoing effort to develop a fire model which is suitable to the Navy's needs. The SHADWELL tests chosen for validation purposes were part of the Internal Ship Conflagration Control (lSCC) program. The validation focused on four compartments which were vertically aligned. The temperatures of the four compartments and the decks between them were compared with model predictions. Predictions compared reasonably well with experimental results for the fire compartment (bottom compartment) as well as for the deck and compartment directly above it. The model overpredicted the temperatures of the compartments and decks not directly adjacent to the fire compartment.This should be a subject of further investigation.
