Combustion Visualisation Monitoring Using High Speed Imaging

Optical visualisation of flames plays an important role in the in-depth understanding of complex combustion phenomena. In particular, a high-speed camera can provide nonintrusive and continuous monitoring of flames. Through the recorded images, further analysis on colour, temperature, flame dynamics, and a variety of other information can be achieved, which is essential for physical study and numerical modelling. The main objectives of the present work are to apply visualisation monitoring to different combustion conditions, quantitatively analyse the combustion performance, and integrate these analyses with their inherent nature to achieve physical insights into these combustion phenomena.
Overall, this work improves the understanding of combustion, and contributes towards the development of tools for flame performance analysis and evaluation. These benefits could be crucial for future fuels and engines.
