As part of the validation of the full FIREDASS computer model, a number of the full
scale tests carried out in the DLR test compartment were simulated and the predicted and
measured results compared. Animations of the results of two of these simulations are
presented here. The simulations were generated using the FIREDASS CFD software. This
includes the fire model, detection-activation model, spray model and suppression model.
Fire only. QuickTime Movie. [940KB].
This animation shows the results of the simulation of the test in which three boxes
were burned in the centre of the compartment with the misting system inactive. Symmetry
was taken advantage of and only a quarter of the compartment simulated.
Fire + detection-activation
system + misting system. QuickTime Movie.
This animation shows the results of the simulation of the same case as before but with
the detection-activation and misting systems active. The animation shows the heat from the
boxes building with time until the detection-activation system activates the misting
system. This then pulses on and off in response to the fire and the internal logic of the
detection-activation system. By comparing the two animations the effect of the misting
system can be clearly seen.
