| Abstract | Many regulatory authorities are now requiring that the emergency ventilation system in a road tunnel be validated using computational fluid dynamics (CFD). Several such codes are commercially available to many engineers who are responsible for designing tunnel ventilation systems but their costs are often prohibitive- € 20’000 for a one-year lease for a single computer is typical. On the other hand free and low-cost CFD codes are available but are these suitable for predicting tunnel fires? This paper reports the results of a study aimed at validating the results given by the freeware ‘Fire Dynamics Simulator version 2.0 ’ (FDS2) developed by the National Institute of Standards and Technology (NIST) 1. The validation of the software has been carried out using the Memorial Tunnel Fire Ventilation Test Program (MTFVTP) Test Case 321 A- a 40 MW fire with a single point supply in the ceiling as the ventilation system. The paper demonstrates that the FDS2 code predicts well the measured data, is suitable for predicting fires in road tunnels and can, just like other state-of-the-art codes, provide valuable information. |
