Simulating one of the CIBW14 round robin test cases using the SMARTFIRE fire field model

Numerical predictions produced by the SMARTFIRE fire field model are compar ed with experimental data. The predictions consist of gas temperatures at s everal locations within the compartment over a 60 min period. The test fire , produced by a burning wood crib attained a maximum heat release rate of a pproximately I I MW. The fire is intended to represent a nonspreading fire (i.e. single fuel source) in a moderately sized ventilated room. The experi mental data formed part of the CIB Round Robin test series. Two simulations are produced, one involving a relatively coarse mesh and the other with a finer mesh. While the SMARTFIRE simulations made use of a simple volumetric heat release rate model, both simulations were found capable of reproducin g the overall qualitative results. Both simulations tended to overpredict t he measured temperatures. However, the finer mesh simulation was better abl e to reproduce the qualitative features of the experimental data. The maxim um recorded experimental temperature (1214 degreesC after 39 min) was over- predicted in the fine mesh simulation by 12%. (C) 2001 Elsevier Science Ltd . All rights reserved.
