Confinement of fire-induced smoke and carbon monoxide transportation by air curtain in channels

A Study on Numerical Analysis of Smoke Protection Characteristic using Air Curtain in 2nd Floor Building

“…Klaus and Horn [1] studied on prevention of the smoke spread from the large space to the surrounding space by use of air curtain, and the smoke isolation effect in channel structure depending on air injection speed was investigated by Stein [2]. Wilkinson [3] conducted the study on smoke spread prevention performance and major design factors for fire smoke rises along the stair, using scale model test and numerical analysis.…”

“…The solutions that are able to deal with smoke control and isolation so far might include mechanical smoke eliminating, air supply & exhaust control, air injection, whirlwind technology, fluid bag technology, smoke protection screen, air curtain, smoke temperature lowering technology and water screen technology. Among them, it has been noticed that air curtain technology has not been well studied.Klaus and Horn [1] studied on prevention of the smoke spread from the large space to the surrounding space by use of air curtain, and the smoke isolation effect in channel structure depending on air injection speed was investigated by Stein [2].

Study on Design of Pressure Chamber in a Linear-Jet Type Air Curtain System for Prevention of Smoke Spread

“…On the other hand, the studies on method to prevent smoke spread by forming the air curtain using high velocity jet flow are underway now in advanced countries. That is, the study on preventing smoke spread between large space and connection space by using air curtain in large space building [2], the study on smoke spread prevention effect in channel structure depending on air blow velocity from air curtain [3], the study on smoke spread prevention performance of air curtain and major factor design through the down-scale model and numerical analysis while smoke is rising through the stair [4], the study on forming the air curtain by blowing the jet flow from the top and bottom of the evacuation passage to prevent the smoke from penetrating into the evacuation passage at tunnel sides [5] and the review of the need for preventing the fire and smoke spread and the phenomenon in a small zone was conducted [6].…”

Full-Scale Measurement and Numerical Analysis of Liquefied Petroleum Gas Water Heaters with Ventilation Factors in Balcony

“…Designing ventilation systems for buildings designed were assessed by Chen et al [4] using seven types of models, including analytical, empirical, small-scale experimental, full-scale experimental, multi-zone network, zonal and CFD (computational fluid dynamics), for predicting ventilation performance in buildings. Many researchers [5][6][7][8][9][10] have discussed the comparisons between the FDS numerical model results and the full-scale fire experimental parameters, such as HRR (heat release rate), CO, carbon dioxide (CO 2 ), temperature and soot, in various buildings. In addition, there are room liquid fire simulation [11] and smoke characteristics analysis [12].…”
