Özet
In this study, the evolution of fuel droplet diameter, flame structure, and maximum flame temperature over time was observed using a high-speed camera and a thermal camera at the same time. Traditional fuels (diesel and gasoline) and new generation fuels (triethyl borate and trimethyl borate) fuels were investigated within the droplet experiments. It has been shown that the flame structure of diesel and gasoline fuel droplets has a large non-luminous region that is seen during the combustion process, unlike triethyl borate and trimethyl borate fuels. The curves of the time-dependent variation of the dimensionless square of the droplet diameter (D/D0) 2 of the fuel droplets considered in the study generally exhibited curve properties conforming to the D2-law. In the flame formed by the trimethyl borate droplet, the highest flame temperature was observed by the thermal camera, while the shortest burning time was detected. According to the experimental conditions in the study, the shortest ignition delay was measured for trimethyl borate, while the longest ignition delay time was observed for diesel fuel droplet. Also, it was determined that the lowest burn rate constant was detected for the gasoline droplet, while the highest burn rate constant was seen for diesel fuel.
