[8] investigated the effects of wind speed and direction on fire spread over the exterior surfaces of isolated rectangular buildings using a computational fluid dynamics model, validating wind tunnel data and facade fire experiments. When considering four wind directions (0\({}^{\circ}\), 45\({}^{\circ}\), 90\({}^{\circ}\), 180\({}^{\circ}\)) and two wind speeds (2 m/s, 4 m/s), and comparing with no-wind conditions, the study found that external wind suppresses the initial development of front fires but significantly exacerbates fire spread once fully developed. In no-wind conditions, flames spread vertically the fastest and horizontally the least. When wind speeds were applied, the fire spread area increased by 50% compared to no-wind conditions. This research provides valuable insights into the interaction between wind and fire on building facades, contributing to improved building fire safety. [PERSON] et al. [9] studied the impact of environmental wind on the fire spread behavior of exterior wall insulation materials, analyzing the influence of environmental wind on vertical fire spread in insulation materials. [PERSON] et al. [10] found that when wind speed is less than 0.2-0.3 m/s, the fire spread rate is not affected by airflow, with buoyant plumes playing a major role. [PERSON] et al. [11] found that the fire spread rate in reverse wind conditions first increases and then decreases with increasing turbulence intensity, with the maximum fire spread rate occurring during the transition from laminar to turbulent flow. As turbulence intensity increases, the wind speed required to extinguish flames decreases. Among the types of facade fires in high-rise buildings, one key area of research concerns flames that spill out through windows from indoor fires and impact the building's facade and upper floors [12; 13; 14; 15; 16]. [PERSON] et al. [17] used scaled models to study the effects of plume spillage from a burning chamber through windows on building facades and upper floors under conditions of insufficient ventilation. The study analyzed vertical temperature distribution on the facade and the impact of window geometric dimensions on the temperature distribution over exterior walls. [PERSON] et al. [18] conducted experiments using gas fire sources to investigate flame heights and radiative heat flux from window spillage under different geometric conditions. The results indicated that the size of the chamber opening, type of fire source, and thermal feedback effects all influence the radiative heat flux on the facade. The impact of environmental wind on facade fires in high-rise buildings needs to be assessed while accounting for urban meteorological conditions [19; 20; 21; 22; 23; 24]. Currently, research on how urban meteorological conditions affect the wind field around buildings includes the following key studies. [PERSON] et al. [25] selected the complex terrain around the Shenzhen Meteorological Tower and used a WRF-CFD-based multi-scale coupling simulation to analyze the wind field in that area. The simulation results verified the applicability of the AN (Analysis Relaxation Method) and SAN (Surface Analysis Relaxation Method) assimilation schemes within the WRF model, with the AN scheme showing higher simulation accuracy. Compared to single-scale WRF simulations, the WRF-CFD multi-scale coupling model provided results that were more consistent with meteorological observational data. This indicates that multiscale coupling simulations improve the accuracy of wind field simulations by providing more accurate boundary conditions from the mid-scale WRF model to the small-scale CFD model and achieving finer-scale simulations through grid nesting. The multi-scale coupling simulation of boundary-layer wind fields based on WRF-CFD is an effective method for enhancing the accuracy of wind effect simulations for high-rise building structures.
