Abstract

An image processing method was employed to visualize the flame shape which was recorded every two milliseconds by using a high speed video camera. The visible image presents an instantaneous behavior of the turbulent flame and it gives some informations on the turbulence of jet diffusion flames.<BR>In order to determine the flame shape, a binary image was made by choosing a threshold value of the original image having 256 grey levels. The binary image makes it possible to calculate the peripheral distance and area of flame. The time variation of their distance and area considerably represents the fluctuation of flame. The analysing with the image processing can be effective method for revealing the physical characteristics of turbulent diffusion flame behavior.
