| 摘 要： | Droplet size distributions have been investigated with a two-probe system above a rotatingstream tray of 300 mm diameter.The measured distributions are found to follow the upper limitedlognormal distribution with three parameters dependent primarily on gas hole F-factor.A probabilitymethod is used to describe the initial state of the droplet population above the tray,and a model fordroplet motion is presented.The results computed with model agree well with experimental data.

| Abstract: | Droplet size distributions have been investigated with a two-probe system above a rotating stream tray of 300 mm diameter. The measured distributions are found to follow the upper limited lognormal distribution with three parameters dependent primarily on gas hole F-factor. A probability method is used to describe the initial state of the droplet population above the tray, and a model for droplet motion is presented. The results computed with model agree well with experimental data. |
