Résumé

There is an increasing demand for performance-based design of tunnel emergency ventilation systems due to the various benefits that are attained from such an approach. In designing such systems, the performance of the ventilation system in the event of a fire is required to be assessed to determine whether the system is effective in maintaining a tenable environment for occupants to escape. Computational fluid dynamics (CFD) codes are used to assess the performance of these systems under fire conditions. The accuracy of such codes in predicting the conditions within the tunnel are critical to the success of the design. The accuracy of a CFD code may be assessed by validation using results from actual fire tests. This validation shows the potential differences that may occur between the numerical prediction and real fire events. However, in order to carry out this validation process, reliable and well documented reference data is needed.
