Abstract

This paper investigates the area of window fallout behaviour of 4 mm and 6 mm thick single glazed ordinary float type glass exposed to a constant radiant heat. Regular rubber beadings and non-standard ceramic fibre beadings were used to mount the 525 mm square glass samples in commercial aluminium window frames. A total of 117 experiments were carried out where the area of glass fallout was recorded as a function of time. The average heat fluxes which the glass samples were exposed to ranged from 13 kW/m 2 to 58 kW/m 2 . The lowest heat flux that is needed for fallout occurrence is found to be 20 kW/m 2 for 4 mm thick glass and 28 kW/m 2 for 6 mm thick glass. The fallout behaviour of glass was quantified with an exponential distribution function and a probabilistic area of glass fallout prediction model for 4 mm and 6 mm thick glass is developed from the experimental results.
辐射热照射下单层玻璃沉降面积的概率模型
本文研究了4mm和6mm厚单层普通浮法玻璃在恒定辐射热作用下的窗口落尘行为。使用常规橡胶珠和非标准陶瓷纤维珠将525毫米方形玻璃样品安装在商用铝窗框中。总共进行了117次实验,记录了玻璃沉降物的面积作为时间的函数。玻璃样品暴露的平均热流从13 kW/ m2到58 kW/ m2不等。发现,对于4毫米厚的玻璃,发生沉降所需的最低热通量为20千瓦/立方米2,对于6毫米厚的玻璃为28千瓦/立方米2。用指数分布函数量化了玻璃的沉降行为,并根据实验结果建立了4 mm和6 mm厚玻璃沉降预测的概率区域模型。
