A recent series of fire experiments has provided previously unavailable high-fidelity data for heat fluxes and gas temperature in a large-scale fire. These include histograms of temporally-resolved gas temperature measurements, which are helpful in assessing the time accuracy of a transient code. A convergence analysis has been performed to determine the appropriate code requirements for comparing with these new data. The convergence analysis suggests a significant benefit to employing higher resolution than was readily possible for these comparisons. Comparisons are made to the data for measured values including partitioned convective/radiative heat flux, and gas phase temperatures. Uncertainty analyses show that the uncertainties due to grid refinement are on the order of those from model input parameter uncertainties. The gas phase temperature results suggest the need for increased mesh resolution to resolve the temperature distributions.
