The evolution of flame length for the oil tank fire with different top cover widths and lip heights

This study presents a quantitative analysis and interpretation of the variation in oil tank fire flame lengths for different oil tank sizes, top cover widths, and horizontal air flow velocities. The experimental results show that, at first, the flame length rises slowly with an increase in air flow speed. Then, once over a critical speed (0.6 m/s), the flame length decreases significantly with a further increase in air flow speed. Based on the characteristic length, a new dimensionless heat release rate is obtained, allowing the correlation between flame length, air flow speed, and dimensionless heat release rate to be calculated, which can be used to predict the flame length of an oil tank fire under different air flow speeds, lip heights, and cover widths.     

凹型建筑外立面火灾烟气蔓延特性研究

为了研究凹型建筑外立面火灾烟气蔓延特性，对高层建筑凹槽内火灾烟气“三场”数值模拟。研究表明:结构因子α（进深与槽宽之比）的变化导致凹型建筑结构内呈现不同的火灾烟气蔓延规律；当α为0~0.4时，建筑凹槽内的火灾烟气无烟囱效应；当α为0.6~1.2时，建筑凹槽内的火灾烟气呈现一定的烟囱效应，其火灾烟气温度场、CO浓度场、扩散速度场变化显著；当α>1.2的，建筑凹槽内的火灾烟气烟囱效应显著。     

Environmental management of oak wilt disease in central texas

Oak wilt disease, for which there is no known cure, is one of the most destructive tree killers in the United States today. This analysis reports on the patterns of disease transmission, along with the methods of treatment used to suppress the severity of the pathogen's attack on trees in central Texas. The practical problems inherent in the linkage between people and their relationship with this environmental disorder are addressed. The environmental controls implemented have application to other areas of the United States and western Europe, where tree species are subject to infections.

A medium scale test method for assessing the fire hazard of flammable solid materials

The medium scale test method currently operated by the Health and Safety Executive (HSE) as a means of assessing the fire hazard of flammable solids is described. The technique has been applied to a range of materials and the results, although specific to the apparatus, have proved useful in ranking relative fire performance     

一起倾倒汽油导致的静电燃爆事故分析

分析了深圳龙岗发生的一起燃爆事故,疑因不规范操作产生的静电放电引起。针对GB12158对该类操作提出的要求,开展相关试验研究。塑料桶加注16 L汽油的过程中,塑料桶上的静电电位最高为4.7 kV。塑料桶与聚四氟乙烯板间相互摩擦,塑料桶上的最高电位为9.4 kV。不接地金属桶加注16 L汽油的过程中,金属桶上的最高电位为-15.4 kV。汽油加注过程中,不接地金属滤网上的最高电位为-1.91 kV。以上3种操作产生的静电皆可能引发静电放电,通过分析,深圳龙岗事故是由静电放电引发。
