Axial jet fans installed at the ceiling are worldwide diffuse devices for longitudinal ventilation
control in road tunnels underordinary operating conditions and also for smoke control under …

ABSTRACT A mechanical ventilation system plays a major role in tunnels safety. Over the
world, different ventilation systems regarding to the tunnel geometry and other parameters …

Road tunnels require ventilation system for different reasons in order to provide a good level
of safety and effectiveness in ordinary service and, in case of fire, to prevent the upstream …

Computer simulations were carried out to study airflow patterns and pollution levels due to
emissions from vehicles for the westbound Melbourne City Link tunnel under severely …

Typically, in the experimental scale road tunnel model, the air flow induced by ventilation
system is provided by an external fan. In this paper, the authors have numerically simulated …

Ventilation during long highway tunnel operation plays a key role in environmental health,
energy savings and reducing consumption. A ventilation model test platform, based on …

To investigate air flow in longitudinally ventilated traffic tunnels, a scaled model of a typical
road-traffic tunnel with an appropriate ventilation system based on axial ducted fans, is …

The issue of airflow dynamic in a road tunnel is considered in this study and its impact on
smoke management and people safety is highlighted. It was an attempt to estimate the time …

In the present work, a semi-transverse ventilation system in a long tunnel with a length of 4.9
km, as a complex case study, is numerically studied by performing a set of three …

ABSTRACT A series of CFD fire predictions of a 100 MW Memorial tunnel fire test are
performed to investigate several factors that influence the outcome of CFD fire simulations of …
