摘要

天然气作为一种清洁能源广泛应用于城市和工业;因此,存在相关的意外爆炸风险。为了减少天然气爆炸的危害,研究无约束空间天然气爆炸荷载的内在规律并建立荷载模型是十分重要的。通过对无密闭空间天然气爆炸的实验,研究了天然气浓度、传播距离和气体体积对爆炸载荷的影响。提出了一种新的无约束空间天然气爆炸超压-时程曲线载荷模型。与经验模型的比较表明,该模型的预测效果优于TNT当量模型和TNO多能模型。

Investigation of a practical load model for a natural gas explosion in an unconfined space

Natural gas is extensively used as a clean energy source in cities and industries; consequently, there are associated risks of accidental explosions. To reduce the hazards associated with natural gas explosions, it is important to study the inherent laws of natural gas blast loads in unconfined spaces and establish load models. Using experiments on natural gas explosions in unconfined spaces, this study demonstrates the influence of natural gas concentrations, propagation distances, and gas volumes upon explosion loads. A new load model was proposed for the overpressure–time history curves of natural-gas explosions in an unconfined space. A comparison with the empirical model indicated that the predictive effect was superior to that of previous models, such as the TNT equivalent model and the TNO multi-energy model.
