基于火焰图像的燃油燃烧室温度场测量

Measurement of Flame's Temperature Field Based on Image Processing

介绍三种比色测温方法的测量原理 ,对它们的优缺点进行了说明 ,并通过实验对其中的单色测量法及 CCD分色测量法进行了验证和评价 .

Compared with other high termperature measurement technologies, image processing technology has advantage in non contacting and speediness. 3 kinds of colorimetry temperature measurement methods' theory were introduced and their advantage and disadvantage were discussed. An experiment was set up to compare the measurement results of 2 of them, that is, single color method and CCD double color method. The experiment results show the image processing technology's application prospect in the temperature field research of gas turbine combustor.
