Benchmark and Sensitivity Study of the Container Analysis Fire Environment (CAFE) Computer Code Using a Rail-cask-size Pipe Calorimeter in Large-scale Pool Fires

Three large-scale fire tests were recently performed at an outdoor facility at Sandia. A 2.43-m-diameter, 4.57-m-long, 2.54-cm-wall-thickness pipe calorimeter was suspended one-meter above a 2000-gallon pool of JP8 jet fuel. The fire pipe temperature, fuel recession rate, and wind conditions were measured at several locations during the fires. In the current work, CAFE simulations are performed for different model parameters and compared to the experimental data. These results show the sensitivity of the CAFE-predicted pipe temperatures to those parameters, and the parameter values that bring the CAFE results close to the measured data for all three tests.The CAFE user manual recommends values of approximately 0.08 for this parameter. ... The same change in the experiments 2 and 3 produces changes in the final temperature of 40[oC] and 60[oC] for test 2 and 16[oC] and 4[oC] in the test 3.
