Abstract

A model-based image-analysis technique is presented which allows the calculation of combustion and flame parameters and physical quantities. Emission-tomographic techniques are employed to determine the radiation-intensity distribution of the flame, and only one image is required in the case of rotational symmetry. After regularizing and constraining the radiation-intensity distribution the intensity distributions of two or more images are examined at different optical wavelengths. The image analysis can be used to determine 3D temperature distributions and gas concentrations for each pixel with pyrometric methods, and the results compare favorably with other measured temperatures. The technique can be used to analyze particular radiation characteristics of combustion processes by employing optical filters
