非稳腔伫间增强探测相干反斯托克斯喇曼散射温度浓度固体燃剂 USED CARS Temperature Concentration Solid propellant

摘要

报道了采用单次脉冲非稳腔空间增强探测-相干反斯托克斯喇曼散射(USED CARS)技术诊断常压下固体燃剂瞬态燃烧场温度和氮气浓度.采用宽带USED CARS技术,在固体燃剂瞬态燃烧场获得了较高信噪比的单次激光脉冲氮气Q支CARS实验谱,用CARS理论计算软件拟合CARS实验谱,给出了固体燃剂瞬态燃烧场温度和氮气浓度在不同高度的分布,固体燃剂燃烧场温度约2 250K、氮气相对浓度16%～20%.

Abstract

The broad-band USED CARS measurements of temperature and N₂ concentration in the combustion of solid propellant at atmospheric pressure are reported.The single-pulse N₂ CARS spectra have been obtained from solid propellant combustion.The CARS data are analyzed by comparison with theoretical spectra generated at various temperatures and N₂ concentrations.The temperatures and N₂ concentrations of the solid propellant flame at different height have been measured and the results indicate temperature up to 2 250K with N₂ concentration of 16%～20%.
