Краткое описание

In this paper, simultaneous visualization technique for temperature and velocity fields of a premixed methane air flame is described. The temperature field is visualized by the flame reaction of potassium combined with inverse Abel transformation, while the velocity field of the flame is simultaneously measured by particle image velocimetry (PIV). This new experimental technique allows an insight into the structure of temperature and velocity fields of the flickering flame. It is found that the temperature and the velocity fields in the flickering flame indicate nonlinear oscillation of the flame. During the flame flickering, the temperature in the flame fronts increases to the highest temperature in the merging region, which is followed by the entrainment of the surrounding air into the flame. This fluid motion contributes to the decrease in temperature and self-sustained oscillation of the flame.
