| Abstract: | Three-dimensional (3D) measurements for turbulent flame have been long desired in the combustion community. In the past decades, with the advancement in high-speed cameras, high-power lasers and computing algorithms, it becomes possible to achieve 3D combustion measurements with sufficient spatial and temporal resolution. This paper reviews the recent development and applications of such a 3D measurement technology based on tomography, so as to provide valuable references to researchers in this field. This review includes the following four parts:First, the principles and computing algorithms of tomography are introduced and reviewed. Second, the experimental measurement systems involved in the 3D tomographic measurements are classified and summarized. Third, the applications of 3D tomographic measurements are introduced including the tomographic chemiluminescence, tomographic laser-induced fluorescence and tomographic shadowgraph/schlieren. Last, we concludes the review and poses several questions for the potential development of the technique. |
