Abstract: The diagnostic testing and regular interpretation of combustion flow fields have significant value for the design, development and engineering applications of engines. This paper summarizes the comprehensive experimental techniques for the study of spray combustion flow fields in engine combustion chambers, mainly using modern optical diagnostics. The basic principles and experimental systems of measurement methods such as schlieren method, laser Doppler velocimeter, laser-induced fluorescence and laser particle size analysis are described for the testing and analysis of two-phase flow fields and spray combustion flow fields. This paper also introduces the measurement of combustion flow fields in commonly used optical transparent model combustion chambers in the laboratory, such as single nozzle cylindrical combustion chambers and annular combustion chambers. The aim of this paper is to provide a reference for readers to understand the optical experimental testing techniques of spray flow fields, and to provide a foundation for the development of new combustion flow field measurement instruments or new measurement technologies.
