In explosion accidents, the leakage of gaseous and liquid fuels, ignition of solid agents, and other situations can generate transient high-temperature flames. The transient high temperature and its thermal damage characteristics have always been key parameters in industrial safety protection and weapon warhead effectiveness evaluation. This type of transient high-temperature phenomenon not only poses a serious threat to industrial production but also directly affects the assessment of the damaging effect of weapon systems. However, in the actual combustion process, accurate acquisition of flame temperature data has always been a technical difficulty in related research fields due to the complex influence of factors such as fuel composition and environmental parameters. This study focuses on the exploration of transient temperature testing methods during flame burning and constructs a flame burning simulation model based on thermodynamic principles. The core parameters such as flame duration and coverage area are systematically analyzed. On this basis, an integrated flame-burning control system was developed, and reliable temperature data was obtained through a series of experiments. Through in-depth research and optimization of influencing factors during the testing process, a high-precision flame-burning transient temperature testing scheme was ultimately developed.
