In this paper, it is demonstrated that the simulation of fire propagation in cable tray installations, with the Fire Dynamics Simulator (FDS), version 6.3.2, can be achieved. A material parameter set allowing to estimate the fire spread, depending on environmental conditions close to the fire seat, was generated. The parameters are determined by utilisation of an evolutionary algorithm, in an inverse modelling framework, based on experimental data from Cone Calorimeter tests. As a further step, the performance of the parameter set is compared between the FDS versions 6.3.2 and 6.5.3.The foundation of this work are experimental results of the CHRISTIFIRE campaign. The inverse modelling approach is inspired by and based on Anna Matala’s and Chris Lautenberger’s work.A material parameter set generated by the evolutionary algorithm is then used in a real scale cable tray fire simulation to predict the fire propagation. The total heat release rate (HRR) of the cable tray simulation and the respective experiment are compared and are in good agreement. The major features in the HRR plot of the experimental data are visible in the simulation results, but slightly shifted in time. Thus, predicting the fire propagation in a simulation, based on data of small-scale experiments, seems possible with FDS.However, the parameters used in this work are model specific and very sensitive to changes in the model, like grid resolution and FDS version. |
