“…Other studies, using a propane burner as the fire source have shown the effect of wind both normal [33], and parallel [34,35] to the fac¸ade to lessen the intensity of the thermal attack. In the case of a timber crib, wind will have a strong accelerating effect in the initial fire growth rate.…”

“…The EN 13823 test [20], as part of the EN 13501-1 test, mainly concentrates on the smoke and dripping generation. Since the tragedy of the Grenfell Tower fire, façade fire has gained a global attention and attracted many studies on different aspects of façade fire hazard [22][23][24][25][26][27][28][29][30]. Bonner and Rein [10] explored many factors and objectives involved in a facade design that could enhance the intensity of the fire and compromise the performance of the facade system.…”

Facade fires in tall buildings are currently occurring more than once a month globally that are responsible for many casualties and billions of dollars in losses. In particular, the tragic Grenfell Tower fire in London caused more than 70 fatalities raised the profile of facade fire hazard. This work used well-controlled irradiation up to 60 kW/m 2 to re-assess the fire hazard of typical flame-retardant aluminum composite panels (ACPs). We found that the vertically oriented ACPs with the "noncombustible" (A2-grade) and "limited-combustible" (B-grade) cores could still be ignited above 35 kW/m 2 and 25 kW/m 2 , after the front aluminum layer peeled off. The peak heat release rate of these ACPs could be higher than common materials like timber and PVC. Moreover, compared to the B-core panel, the A2-core panel showed a greater fire hazard in terms of a shorter ignition delay time, a higher possibility of the core peel-off, and a longer flaming duration. It is because the ACP is a complex system, and its fire hazard is not simply controlled by the core material. The structure failure of ACP in fire, including peel-off, bending, softening and cracking, could further increase the fire hazard. This research improves our understanding of the systematic fire behaviors of facade panels and helps rethink the fire risk and test methods of the building facade.

The overflow of the flame plume from the window is the main cause of the vertical spread of the fire on the facade of the building. This paper considers the geometry of the window by taking measures to prevent the flame from propagating along the vertical wall. In this paper, a residential building is taken as an example to evaluate the flame plume characteristics through experimental tests and numerical simulations. The objective of the present study is to study the flame plume characteristics under the air blow on the outer window side of the building. The theoretical equations of the flame tilt angle, non-dimensional temperature and non-dimensional velocity are derived. A series of experimental tests were carried out in a reduced-scale building model corresponding to the changes of lateral blow ventilation velocity. Reduced scale numerical simulations were conducted to verify the experiments. Results showed that the flame tilt angle increases with ventilation velocity increases. Meanwhile, the experimental results were compared with the reduced-scale tests and numerical simulations. These showed a good agreement between experimental results and numerical simulations. All these findings provide theoretical basis for building fire prevention outside window.
