Outline
To address the challenge of locating the fire source in high-rise building fires, a full-scale indoor fire test platform was constructed and a series of tests were conducted to investigate the feasibility of inferring fire locations from the temperature field on the fire-unexposed surface of window glass in high-rise building fires. By varying the fire location and heat release rate, the temperature field on fire-unexposed surface and fire environment parameters were obtained, and the characteristics of fire-unexposed surface temperature field under different scenarios were analyzed. The results show that window glass regions at higher elevations and on the fire side exhibit significantly higher temperature rise rates under different fire location conditions. At 480 s after ignition, the temperature non-uniformity coefficient of fire-unexposed surface under different fire location conditions is not less than 33.52%, and reductions in the distance between fire location and window lead to a marked increase in the temperature non-uniformity coefficient on the fire-unexposed surface. With increasing heat release rate, the coefficient of variation of the increase in temperature rise rates across different glass regions on the fire-unexposed surface generally exceeds 10%, and this disparity becomes more pronounced with increasing heat release rate. When the normal distance between the fire location and the window decreases, window glass at higher elevations and on the fire side exhibits a greater increase in temperature rise rate. When the radial distance between the fire location and the window decreases, the increase in temperature rise rate at higher elevations is significantly greater than that on the fire side.
