| Abstract: |
| Based on the study on spray characteristics at the exit of a gutter-atomizer,the spray concentration distribution down stream from the gutter-atomizer is measured by means of laser holography .In this paper the variation of atomiza-tion performance in the spray is studied, and the effects of the width of gutter, the diameter of atomizer and the air speed on the atomization performance is also discussed. |
