摘要
介绍一种利用激光干涉法原理测定燃烧室内气体热力学参数的新方法,在定容燃烧弹内对燃烧室内气体瞬态密度和温度进行了测量,并对结果的精度进行了分析.结果表明这是一种测定和研究燃烧室内气体局部瞬态热力学参数非常有效的方法,它并能用于测定火焰传播速度.
This paper introduces a new method to measure gas thermodynamic parameters in a combustion chamber by laser interferometry. The gas instantaneous temperature and density in a constant volume bomb have been measured, and the precision of measurement results is analyzed. The results show that it is a very effective method in measuring and studying gas local instantaneous thermodynamic parameters of the combustion chamber, and can also be used to measure flame propagation velocity.
