摘要
可调谐半导体激光吸收光谱(TDLAS)技术由于其灵活和高效的特性成为当前燃烧场研究的主要方法之一。传统的成像算法采用修正型代数迭代法(ART)对二维场进行求解,然而有限数量的探测光束使得ART算法的求解精度受限,难以满足实际应用需求。对此,本文在ART算法的基础上,提出一种ART-Kriging燃烧场二维建模算法,有效地解决了TDLAS-ART技术在燃烧场监控时精度较差的问题。通过实验对该算法进行了验证后,结果表明,本算法在温度场的求解上较ART算法分辨精度有显著提升,与热电偶实测温度结果误差小于8%,结果表明了算法的有效性。
Tunable laser absorption spectroscopy(TDLAS)technology has become one of the main methods for current combustion field research due to its flexible and efficient characteristics.Traditional imaging algorithms such as the Modified Algebraic Iteration Method(ART)solve two-dimensional field problems limited number of detection beams and the accuracy of the ART algorithm,which makes it difficult to meet practical application requirements.In this regard,this article proposed an ART-Kriging two-dimensional modeling algorithm for combustion field,which effectively solves the problem of poor accuracy of the TDLAS-ART technology in combustion field monitoring.After verifying the algorithm through experiments,the results show that the resolution accuracy of this algorithm in solving temperature fields is significantly improved compared to the ART algorithm,and the error with the measured temperature results of thermocouples is less than 8%.The results indicate the effectiveness of the algorithm.
