This report provides information on the state of the practice of design fires in road tunnels, focusing on tunnel fire dynamics and the means of fire management for design guidance.

<p>Based on CFD method, this paper conducted simulation analysis of lorry and car fires for large cross-section road tunnel. The smoke distribution feature was discussed and the corresponding results of critical ventilation velocity were also compared with ...

<p>In the present study, conducted by the National Institute for Occupational Safety and Health, a CFD program (fire dynamics simulator) based on large eddy simulations (LES) is used to model floor-level fires in a ventilated tunnel.</p>
