The Analysis of HGV Fire Scenarios in Tunnel with Point-Extraction Ventilation
In this study, the authors numerically simulated heavy goods vehicle (HGV) fire scenarios in order to investigate the tenable conditions of a two-way traffic road tunnel with point-extraction ventilation system consisting of water spray system. A computational fluid dynamics (CFD) model was used to simulate the interaction between the point-extraction ventilation and the water spray system. A total of four cases were carried out in a 600 m tunnel model. Distributions of smoke, temperature, visibility, and CO concentration profiles in tunnels axial-sections for the considered model and point-extraction ventilation system were provided. Results show that the characteristics of tenable conditions for the tunnel fires having water spray are distinctive from those of the tunnel without water spray and ventilation. Tunnel with the point-extraction ventilation and water spray system can provide the relative safety region for occupants at the outside of the water spray zone once HGV fires occur.
