Broad-band CARS diagnostics of solid propellant combustion
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%.
