The fact that many underground facilities, as large-scale spaces, differ in their geometric
characteristics, continually sets new tasks for the researcher investigating the fluid …

Computational Fluid Dynamics has been used in order to evaluate the influence of the
position of jet fans on smoke movements in a tunnel where a fire occurs. Jet-fans are …

Fire throttling is the increase in flow resistance due to a large fire in a longitudinally
ventilated tunnel. Although the fire throttling effect has been been known and studied for …

To reduce the computational time for modelling large tunnel networks, we used FDS6. 1 to
investigate the solver's capabilities for multi-scale modelling by combining 1D and full CFD …

People inside a road tunnel may be in grave danger if there is a fire. When a fire is
developing, mechanical ventilation can be crucial in protecting occupants and facilitating the …

With the aim of evaluating capabilities of a tunnel ventilation system to control the spread of
smoke in the emergency operating mode, thereby providing conditions for safe evacuation …

Airflow structure and its magnitude are important for smoke management in longitudinally
ventilated tunnels. This paper presents a sensitivity study by Computational Fluid Dynamics …

Longitudinal ventilation system is a frequent method of tunnel ventilation which is commonly
implemented by use of jet fans. In most studies on longitudinal ventilation application, the …
