抄録

Behavior of diffusion flames under the low and high gravity was experimentally studied for the better understanding of the convective air inflow into the diffusion flame. Also how the gravity affects the stability and blow off of the flame was investigated. The gravity level was artificially controlled by using a drop tower and a spin tester in the range from G=0.02 to 15 where G= 1 means the normal gravity on the earth. The laminar diffusion flame of butane was made on the tip of the small vertical pipe. The results showed that the length and the width of the flame were reduced with an increase of the gravity level. The oscillation and blow off of the flame were observed in the high gravity level. The blue flame region observed at the anchor portion of the diffusion flame became more intense with increasing gravity level. It can be explained that the phenomena of the natural convective air inflow is enhanced by the high gravity.
