Abstract: A known model for describing tunnel fires is extended to the case of tunnel networks. Physically motivated coupling conditions are formulated. A numerical realisation of these conditions and of the full network problem is presented. Finally, numerical simulation of realistic tunnel fires in networks are performed.
