Cerberus: a new model to estimate size and spread for fires in tunnels with longitudinal ventilation
A new fire model is presented. It uses complex Computational Fluid Dynamics (CFD). This model, CERBERUS, combines the results and findings of three previous research projects carried out at Heriot-Watt University. Each of the three projects is briefly described. Combining the results of these three projects, together with knowledge of fire behaviour in the open air, enables the estimation of the maximum fire size of a fire in a tunnel and the conditions under which it might spread to an adjacent vehicle, for a given longitudinal ventilation velocity. To enable these results to be easily used by a wide audience, they are being combined in a single, user-friendly, computer-model. The current version of this model is limited to considering fire spread between heavy goods vehicle (HGV) objects in a single lane tunnel, dimensions based on the Channel Tunnel rail link (UK/France). Future versions of the model will allow for different sizes of tunnel to be considered. Some preliminary results are presented and discussed.
