摘要:
对密闭燃烧室内的预混火焰传播来说,火焰表面积是一个十分重要同时难以测量的动态参数.本文通过数学推导,得到了预混火焰表面积和压力之间的关系表达式,并采用数值模拟验证了推导结果的有效性.结果表明压力上升速率与火焰表面积呈正相关.结合该表达式和实验结果对密闭管道内甲烷-空气预混火焰传播进行了定量分析,发现在障碍物作用下,预混火焰表面积急剧增长,火焰面积和火焰面积增长速率随障碍物阻塞比增大而增大.
Abstract:
Premixed flame surface area is an important parameter in a closed combustion chamber.However,it is rather difficult to be measured.In this paper,a mathematical expression for pressure and premixed flame surface area in closed combustion chamber is obtained through mathe matical deduction.The expression is verified by numerical simulation.The results show that pressure growth rate is positively related to flame surface area.The quantitative analysis of experimental results found that premixed flame surface area increases sharply due to the effect of flame-turbulence interaction.Flame area and flame area growth rate increase with the increase of blockage ratio.
