摘要/Abstract

摘要： 为研究矩形泄漏孔水平喷射火的热辐射分布,首先采用火灾动态模拟软件(FDS)模拟具有相同面积的正方形和长方形泄漏孔下13种不同泄漏速度的喷射火,监测喷射火的热辐射数据和伤害半径;然后运用Thornton模型计算热辐射值和伤害半径,添加矩形泄漏孔长宽比因子至模型中,根据模拟结果修正Thornton模型。研究得出:热辐射的Thornton模型预测值和模拟值变化趋势一致,但Thornton模型预测值更大;修正后的Thornton模型可用于预测矩形泄漏孔喷射火孔口近区域的热辐射值;伤害半径与泄漏速度成指数关系,伤害半径的Thornton模型预测结果和模拟结果吻合得较好。

关键词: 喷射火, 矩形泄漏孔, 热辐射, 伤害半径, Thornton模型

Abstract: In order to study the thermal radiation and hazard radius of horizontally oriented rectangular source fuel jet fires, Thornton model combined with FDS simulation tool was used to simulate square and rectangular fuel source (with same area) jet fires. Simulation involving 13 fuel exit velocities were carried out. The Thornton model was modified to take aspect ratio of rectangular orifice into account based on simulated data. The results show that the thermal radiation results obtained by Thornton model are greater than those of FDS, but their variation tendencies with exit velocity are the same. The modified Thornton model can be used to predict thermal radiation near the exit port of rectangular jet fire,that there is an exponential relationship between hazard radius and the exit velocity,and the Thornton model prediction of the hazard radius matches the simulation results.

Key words: jet fire, rectangular jet exit port, thermal radiation, hazard radius, Thornton model
