Abstract
Due to the characteristics of combustion such as three-dimension, high temperature, turbulence, and unsteady state accurate measurement of the combustion is difficult and is a hot research topic. Computed Tomography of Chemiluminescence (CTC) combines the chemiluminescence and CT technology. By directly shooting flame images from different angles and using reconstruction algorithms to reconstruct the flame, a fine description of the three-dimensional structure of the flame can be achieved quickly and accurately. The self-luminescence of the flame is used in the CTC as the light source, so there is no additional light source equipment required, which makes the system easy to build and can be implemented in a complex environment. These advantages enable the CTC technology to be used for real-time measurement of high temperature and turbulent flames, which is of great significance for studying complex combustion flow fields and improving combustion efficiency. In this paper, the basic principles of the CTC technology are introduced firstly, and then the research progress of the CTC technology in the direction of 3D reconstruction of flame is introduced in four aspects: the imaging model, the reconstruction algorithm, the experimental equipment and its application. Finally, the development trend of the CTC technology is discussed.
