项目摘要

This research was aimed to develop a new measurement method of velocity, temperature, and concentration in supersonic combustion flow by using a compact diode laser. This method is based on the infrared absorption characteristics of H_2O molecules.A InGaSaP diode laser was selected to detect 1.393 μm band of H_2O vibration-rotation transition. The investigation of the transition lines of H_2O molecules proved that two pairs of transition line are suitable for the temperature measurement in the range of 1300 K - 2000 K and 300 K - 1300 K separately. By collaboration research with a scientist in USA, the diode laser controller, laser corrector optics, and the measurement code were developed, and the assembling of the optical fibers and diode-laser laser optics were conducted.By using a supersonic-combustion test facility of Institute of Fluid Science, Tohoku University, measurement tests of supersonic air-flow and the combustion flow behind a flame holding strut were conducted to confirm … More the performance of the system developed in this research. For installing the laser probes to the measurement section of the wind tunnel, AR coated optical windows, pin-hole structure, and nitrogen-purge system were employed in order to minimize the effects of the surface reflection, flame radiation, and laser absorption by surrounding air. Results of the measurements showed that, in supersonic air-flow, data of temperature and velocity agreed well with the numerically estimated values without any data compensation. H_2O concentration agreed with estimated value when the background H_2O concentration caused by the residual H_2O via the air reheater of the wind tunnel was reduced. The velocity data for the combustion region was compared with the mean velocity measured by LDV and they agreed well. H_2O concentration was also agreed well with the values estimated based on chemical equilibrium of H_2-air flames in the wake region. From these results, the accuracy and feasibility of the diagnostic method developed in this research were confirmed. Less
本研究旨在发展一种利用小型半导体激光器测量超声速燃烧流场速度、温度和浓度的新方法。该方法基于H2O分子的红外吸收特性,选用InGaSaP半导体激光器探测H2O分子1.393 μm的振动-转动跃迁。对水分子跃迁谱线的研究表明,两对跃迁谱线分别适用于1300 K - 2000 K和300 K - 1300 K范围的温度测量。通过与美国科学家的合作研究,开发了二极管激光控制器、激光校正光学系统和测量代码,并进行了光纤和二极管激光光学系统的组装。利用东北大学流体科学研究所的超声速燃烧试验设备,进行了超声速空气流和火焰稳定支柱后燃烧流的测量试验,以确认 ...更多信息 本研究开发的系统性能。为了将激光探针安装到风洞的测量段,采用了AR涂层光学窗口、针孔结构和氮气吹扫系统,以最大限度地减少表面反射、火焰辐射和周围空气对激光吸收的影响。测量结果表明,在超声速气流中,温度和速度的数据与数值估计值吻合良好,无需任何数据补偿。当通过风洞空气再热器的残余H_2O引起的背景H_2O浓度降低时,H_2O浓度与估算值一致。燃烧区的速度数据与LDV测量的平均速度进行了比较,两者吻合较好。H_2O浓度的计算结果也与基于H_2-空气火焰化学平衡的估算值吻合较好。从这些结果,在本研究中开发的诊断方法的准确性和可行性得到了证实。少
