内容記述 | The present work was performed to elucidate the mechanism of turbulent jet diffusion flames from a circular nozzle by using a high speed video camera. The visible images present an instantaneous display of the turbulent flames. This paper gives information on the turbulence of jet diffusion flames, analyzed from the flame shape which was recorded every 2 milliseconds. An image processing method was employed to visualize the flames shape. In order to obtain the external length and area of flame, a binary image was made from the gray scaled images. A quasi-periodic fluctuation appears in the external length of the flame, and in the area of flame, based upon examination of 300 sequential frames of binary images, in the case of Reynolds number 500. Resulting from an increase in the Reynolds number, the periodic fluctuation gradually disappears, and a high frequency component appears. Its amplitude becomes high. there is a similarity between the external length and area of the flame. Analyzing the binary image of a flame can reveal the physical characteristics of turbulent diffusion flame behavior. |
