摘要:
为了研究油气浓度对半开口管道爆炸超压特性与火焰行为的影响,建立半开口透明管道实验台架,采用5种不同初始油气浓度,进行了一系列油气爆炸对比实验。研究结果表明:油气浓度对油气爆炸超压峰值以及升压速率有显著影响,二者都呈现随浓度的增加先增大后减小的变化规律;油气浓度对火焰锋面传播速度有着显著影响,在当量浓度比下,火焰锋面的传播速度最大,并且火焰锋面的传播距离也最远;管道内的火焰行为可以分为4个阶段;油气浓度对火焰传播形态以及传播速度有明显的影响,对火焰传播形态的影响主要体现在破坏变形以及管道外爆炸阶段,随着浓度增加,爆炸半径先增大后减小,火焰传播速度呈现相同的变化规律。
Abstract:
In order to investigate the effect of gasoline-air concentration on the explosion overpressure characteristics and flame behavior of semi-open pipeline, a semi-open transparent pipeline experimental platform was established, and a series of comparative experiments on the gasoline-air explosion were carried out by using five different initial gasoline-air concentrations. The results showed that the gasoline-air vapor concentration had a significant effect on the peak value of overpressure and the rate of pressure rise of the gasoline-air explosion, and both of them showed the change law of increasing first and then decreasing with the increase of the gasoline-air concentration. The gasoline-air vapor concentrations had a significant effect on the propagation speed of flame front, and the propagation speed of flame front was the greatest and the propagation distance of flame front was the longest under the equivalent concentration ratio. The flame behavior in the pipeline could be divided into four stages. The gasoline-air vapor concentrations had a significant effect on the flame propagation morphology and propagation speed. The effect on the flame propagation morphology was mainly reflected in the damage deformation and explosion outside the pipeline stages. The explosion radius increased first and then decreased with the increase of concentration, as well as the flame propagation speed.
