管道内障碍物对加氢甲烷爆炸特性的影响
Effects of hydrogen addition on explosion characteristics of gas under condition of obstacles
摘要
Abstract
The effects of hydrogen addition on explosion characteristics of gas under the condition of obstacles were investigated. The hydrogen fraction in the methane-hydrogen mixture was varied from 0 to 1 at equivalence ratio of 1. The result indicated that the maximum pressure and propagation speed of flame both increased with increasing fraction of hydrogen and obstacle quantity. In addition, the hydrogen addition can also change flame color and flame front. However, the influence of the obstacle quantity on average propagation velocity of flame was slight, and the effects of the obstacle quantity on flame propagation speed of methane as well as hydrogen were different. Increasing trend of the maximum pressure and flame color with the fraction of hydrogen was more and more obvious as the obstacle quantity increased. The influence of the obstacle quantity on explosion characteristics of hydrogen was more obvious than that of methane.关键词
