摘要
燃烧场温度的准确测量是评价燃烧状况的重要指标.可调谐二极管激光吸收光谱(TDLAS)技术是一种有效的非接触式燃烧诊断方法,其具有更广的测量范围、高精度和良好的抗干扰性能,且能实现连续测量.然而,在高分辨率透射分子吸收数据库(HITRAN)中光谱数据都是以296 K的谱线参数为基础,通过计算获得较高温度下的光谱数据.因此,本文利用TDLAS波长调制技术标定了高温场中O2 的二次谐波信号强度与温度的函数关系,为后续燃烧场温度测量实验奠定基础.
Abstract
Accurate measurement of combustion site temperature is an important indicator for evaluating combustion conditions.Tunable diode laser absorption spectroscopy(TDLAS)technology is an effective non-contact combustion diagnosis method,which has a wider measurement range,high precision and good anti-interference performance,and can achieve continuous measurement.However,the spectral data in the High-Resolution Transmission Molecular Absorption Database(HITRAN)are based on the spectral line parameters of 296 K,and the spectral data at higher temperatures are obtained through calculation.Therefore,this article uses TDLAS wavelength modulation technology to calibrate the functional relationship between the second harmonic signal intensity and temperature of O2 in high-temperature fields.lays the foundation for subsequent combustion field temperature measurement experiments.
