![]() ![]() Laboratory tests are utilised to support these simulation efforts, as in general the explicit measurement of the material properties is not feasible. One way to achieve this goal is to simulate material pyrolysis. Ideally, the fire development could be simulated, based on the material of the objects involved, as well as ventilation conditions and energy distribution near the fire’s location. The rigidness of the prescribed fire developments, e.g., hydrocarbon curve, is an obvious limitation. In the fire safety engineering community, design fires are a frequently used tool when conducting fire risk assessments. The responses of the material parameter sets are briefly compared with a selection of state of the art procedures. The fire in the tray simulation extinguishes earlier and the total energy release is slightly higher when compared to the experiment. Despite this handicap, the general features in the fire development can be reproduced, however not exact. It is important to note, the inverse modelling process is focused on the Cone Calorimeter and not aware of the actual validation step. As a validation step, the best parameter sets are then utilised to simulate fire propagation within a horizontal cable tray installation and are compared with experimental data. Low flux conditions 25 kW/m 2 and less exhibited difficulties to be accurately simulated. The best fitness was found for a test condition of 50 kW/m 2. The simulation responses are compared with the experimental data and ranked based on their fitness. ![]() Here, parameter sets are generated procedurally and serve as input for simulations conducted with the Fire Dynamics Simulator (FDS). Cone Calorimeter test data are processed in an inverse modelling approach. A general procedure is described to generate material parameter sets to simulate fire propagation in horizontal cable tray installations. ![]()
