Tunnel fire smoke control is an important issue in the area of tunnel safety. Inspired by compartmentation buildings, it worth investigating whether a can be partitioned water mist system into zone and safety zones. If so, people move from safe through system. Obviously, essential question to examine what extent fire-induced heat blocked Thus, present paper, CFD simulations were conducted inves...

According to the advance of civil engineering and transportation, the tunnel tends to increase as a number and be longer as a scale. It is divided to underground and undersea tunnel by location, and is sorted into railway and road tunnel by transportation. Channel Tunnel is world’s longest undersea railway tunnel that reaches a length of 50.45 km (1). Great Britain is connected to France by it....

The present study examines the prevailing conditions in a railway tunnel after train fire accident and ability of ventilation system to create proper for safe passenger evacuation. examined scenario included an event 20-MW diesel pool on suburban train, immobilized middle 1.5-Km long, linear shaped rectangular ventilated by longitudinal jet fan system, people’s movement during evacuation was ef...

A series of fire experiments were carried out in a wind tunnel at the United States Forest Service’s Fire Science Laboratory in Missoula, Montana. The experiments involved tines cut out of pieces of cardboard. The pieces were laid out in comb-like strips parallel to each other along a testbed. They were ignited at the windward end of the testbed. The progress of the fire was monitored by thermo...

The performance of a fire resistant coating for tunnel passive fire protection under successive severe thermal loading is presented. The material falls under the class of potassium based geopolymers (K-geopolymer) and was prepared by mixing ferronickel (FeNi) slag, doped with pure alumina, with a highly alkaline potassium hydroxide aqueous phase. Its performance was assessed by subjecting a con...

CFD simulation is used to predict 3D flow inside different configurations. Tunnel ventilation system is one example of CFD application field. Ventilation system is important in all kind of tunnels, road tunnel, rail tunnel or waterway tunnel. In all case CFD is able to predict chronic pollutant dispersion or accidental consequences. This paper presents the model of a waterway tunnel in France i...

This paper reports on the Response Time Index (RTI) of sprinkler heads. The standard plunge test has been carried out in a hot wind tunnel, which is similar to the one developed at the Fire Research Station, United Kingdom. Some of the modifications have been finished in this wind tunnel for the higher accuracy purpose. About 37 liquid-in glass sprinkler heads are studied including the pendent ...

During the actual operation of a subway company, only one ventilation-control scheme is considered in emergency plan, without considering specific location difference fire source. However, case an tunnel fire, best and personnel-evacuation are very different given potential locations We consider use connecting channel for smoke exhaust or personnel evacuation study scheme, when source at positi...
