- Abstract
- The present study investigates the ventilation effects on smoke spreading characteristics in railway tunnels
with the rescue stations. Experiments for tunnel fires were carried out for n-heptane pool fires with a square length 4
cm at different fire locations, and the heat release rates (HRR) were obtained by the measurement of burning rates. In
addition, using the commercial code (FLUENT), the present article presents numerical results for smoke behavior in
railway tunnels with rescue station, and it uses the MVHS (Modified Volumetric Heat Source) model for estimation of
combustion products resulting from the fire source determined from the HRR measurement. As a result, it is found that
smoke propagation is prevented successfully by the fire doors located inside the cross-passages and especially, the
smoke behavior in the accident tunnel can be controlled through the ventilation system because of substantial change
in smoke flow direction in the cross-passages.
