EXPERIMENTAL-VERIFICATION OF REVISED FIRAC

The research objectives of this project were to carry out experimental studies to validate the gas dynamic module and the heat transfer modu le of the FIRAC fire simulation code developed by Los Alamos National Laboratory. The experiments necessary to evaluate the various modules of the code were accomplished in the Large Scale Flow Facility at New Mexico State University. Five experiments were performed and then atte mpts were made to simulate the results by FIRAC. It was found that err ors within FIRAC allowed only two of the experiments to be successfull y simulated. One of these errors was found and corrected by Los Alamos National Laboratory personnel, but the remaining errors are still und er study. The results of the two simulations that did run showed FIRAC closely predicts the trends of the gas dynamics and heat transfer of the experiments.
