“…Figure 12 gives the façade temperature with the positions of the middle, right, and sidewall. According to the flame behaviors, three regions are distinguished with corresponding temperatures: (a) continuous region (>560°C), (b) intermittent region (300–560°C), and (c) non‐spilled region (<300°C) 16 . The continuous region is focused on as the hazardous region in characterizing flame spread.…”

“…13 On the contrary, the maximum flame height of 750 and 900 kW is increased by about 0. and (c) non-spilled region (<300 C). 16 The continuous region is focused on as the hazardous region in characterizing flame spread. In general, the thermal load imparted by sidewall façade flames exhibits an augmentation compared to the original façade, and this enhancement becomes increasingly prominent as the sidewall distance decreases.…”

“…9,[13][14][15] Also, similarity and feasibility analyzes among different tests and theories are performed. 16,17 In addition, the inclusion of sidewalls in the façade design commonly exists in high-rise buildings. This structural feature can alter the flame trajectory and spread dramatically by restricting air entrainment.…”

“…In this field, calibration tests of BS 8414‐1, SP Fire 105, ISO 13785‐2, and LEPIR2 have been simulated to clarify the effect of HRR, wind, opening size, and numerical uncertainties on façade temperature distribution 9,13–15 . Also, similarity and feasibility analyzes among different tests and theories are performed 16,17 . In addition, the inclusion of sidewalls in the façade design commonly exists in high‐rise buildings.…”

The full‐scale façade standard test is widely employed as a comprehensive method to assess the façade fire spread. Within this approach, the calibration test without combustible façade decouples the intricate interaction between gas‐phase combustion and material pyrolysis, which simplifies diagnostics and provides an ideal scenario for model validation. This paper presents large eddy simulations (LES) accompanied by comparisons of calibration tests in accordance with JIS A 1310. The calibration tests were conducted to obtain the flame morphologies, gas‐phase temperature, and heat flux of over‐ventilated façade fires, and the LES modeling is complemented by the modified eddy dissipation model for combustion, the one‐equation model for the sub‐grid scale turbulence, and the discrete ordinate method with the gray mean absorption‐emission approach for thermal radiation. The accuracy of LES data is discussed by comparing with measurements, and the mesh resolution is optimized as 2.5 cm for achieving mesh independency with good qualitative agreement. Furthermore, simulations are conducted to investigate the impact of sidewall distances on façade flame spread. The results highlight that the enhancement of sidewall in façade flame spread occurs under external heat release rate, and the 0.2 m sidewall distance for the designated JIS test is identified as a critical threshold increasing façade thermal load.

“…Subsequent fire development and/or fully developed fires [17] are assessed by the heat of combustion and calorific value [18,19], maximum temperature reached in the fire [20,21], mass loss [22], and rate of fire spread [23]. The final factors that need to be evaluated in fire assessments include the amount of smoke produced, the optical density of the smoke [24][25][26], and the methods used to extinguish the fire [27][28][29]. Research in the field has focused on conducting laboratory tests according to prescribed standards [30][31][32] or large-scale tests [33,34].…”
