Underground mine fires are associated with thermal and non-thermal hazards. Thermal
hazards are primarily characterized by the release of heat into the underground confined …

Revolutionary progress in Computational Fluid Dynamics (CFD) modeling over the last two
decades manifests itself in fire research through transition from zone to field models. This …

The “critical velocity” is the minimum air velocity required to suppress the smoke spreading
against the longitudinal ventilation flow during tunnel fire situations. The current techniques …

In order to research the fire characteristic of hydrogen jet fire in tunnels under different
conditions, computational fluid dynamics (CFD) simulations of the hydrogen jet fire from a …

In ventilated tunnel fires, smoke and hot combustion products may form a layer near the
ceiling and flow in the direction opposite to the ventilation stream. The existence of this …

This paper proposes two prediction models for backlayering length and critical velocity in
metro tunnel fires, in which the characteristic hydraulic diameter of the tunnel H¯ was …

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 …

▪ Abstract Fluid mechanics research related to fire is reviewed with a focus on canonical
flows, multiphysics coupling aspects, and experimental and numerical techniques. Fire is a …

In this study, the critical velocity was investigated with various aspect ratios (0.5, 0.667, 1.0,
1.5, 2.0) of the tunnel cross-section in tunnel fires. Reduced-scale experiments were carried …

Fire and smoke movement in a room is influenced by the turbulence characteristics (such as
Reynolds stress, turbulent heat flux, etc.) of the flow and temperature fields. In order to …
