In this work, a numerical 3D simulation of a longitudinal ventilation system (LVS) is
developed to analyze the fire behaviour inside a road tunnel. The numerical modelling …

The longitudinal ventilation system (LVS) efficiency in road tunnels is conditioned by
geometric and operational parameters. Typical geometric parameters are the length of the …

Computational fluid dynamics are applied to simulate the smoke movement in a ventilated
tunnel fire through large eddy simulation (LES). Several scenarios with different ventilation …

Numerical study is carried out using large eddy simulation to study the heat and toxic gases
released from fires in real road tunnels. Due to disasters about tunnel fires in previous …

This work is an experimental study on the subject of tunnel fires, which is conducted on a
ventilated 1/13 scaled tunnel model in the Fluid Mechanics Laboratory, Department of …

Smoke control is a key issue in tunnel fire accidents. While jet fans have been widely used in
road tunnels, mobile fans provide a good complement, due to its flexibility to operate …

In this study, numerical simulation was carried out to analyze the effect of the aspect ratio on
smoke movement in tunnel fires using FDS 3.0. Temperature distribution under the ceiling …

Field modelling results are presented for well-ventilated horizontal tunnel fires. Both the
Reynolds-Averaged Navier–Stokes (RANS) and Large-Eddy Simulations (LES) approaches …

The influence of the turbulence model is investigated in numerical simulations of the flow in
a well-ventilated horizontal tunnel with a local fire source. It is illustrated that the basic …

Jet fan (ductless fan) ventilation in underground mines and tunnels is a subject requiring
further attention. At present there are no accepted procedures or guidelines for this type of …
