摘要:
 在定容燃烧弹内利用高速纹影摄像法研究了不同初始温度和初始压力下不同当量比的天然气-空气混合气的
火焰传播过程,并结合火焰传播照片分析了初始压力和初始温度对混合气层流燃烧速率的影响.研究表明,天然气-
空气混合气的无拉伸火焰传播速率和无拉伸层流燃烧速率随当量比的增加先增大后减小,且最大值出现在化学当量
比附近.火焰传播速率和层流燃烧速率均随着初始压力的升高而降低,随着初始温度的升高而提高.
Abstract:
 The laminar combustion processes of natural gas-air mixtures with various equivalence ratios under different
initial pressures and initial temperatures were studied in a constant volume combustion bomb using schlieren photography.
Both unstretched flame speed and unstretched laminar burning velocity were obtained by analyzing flame photos. The experimental
results show that unstretched flame speed and unstretched flame burning velocity increase first and then decrease
with the increase of equivalence ratio,reaching the maximum value around stoichiometric ratio. Both unstretched flame
speed and unstretched laminar burning velocity decrease with the increase of initial pressure,while they increase with the
increase of initial temperature.
