Numerical simulation of micro-scale combustion characteristics of jet fuel surrogate/hydrogen mixtures

  • 摘要:

    对二维三级后台阶微燃烧器中以三种碳氢化合物(69% C10H22、11% C9H18、20% C9H12)混合的Jet A-1模型燃料与氢气的掺混在纯氧中的燃烧进行了数值模拟,分析了燃料掺氢比、进气流速对微燃烧器内燃烧特性的影响。结果表明,所有火焰均可以稳定在微燃烧器第一后台阶(距离微燃烧器入口3 mm处)之前。随着掺氢比增加,火焰位置逐渐前移,火焰长度缩短,且微燃烧器内部的高温区面积减少,最高温度降低,上游燃烧强度更高但下游更低,CO和CH4质量分数减小,裂解反应的发生位置前移且裂解产物的质量分数降低。随着入口进气流速增加,燃烧反应的高温区扩大,火焰中心位置和火焰前沿向微燃烧器出口移动和拉伸,掺氢比对壁面温度的影响减小,微燃烧器中心线OH质量分数整体增加,CO2质量分数减小,CH4质量分数增加,且裂解反应的发生位置后移且产物质量分数增加。结果表明,低速下可以掺混少量氢气得到更高的壁温从而获取更多能量。低速可能影响燃烧区燃料燃烧时的化学反应,从而造成上游的OH生成量减小。掺氢比的增加以及流速的降低会使CO质量分数波动更加明显。CO2的质量分数最高时的掺氢比为25%。在高掺氢比和低进气流速下,乙炔大部分是靠燃料直接裂解生成,只有少量是通过丙烯的二次裂解生成。
