喷射态筛板上的液滴粒度分布

Liquid Droplet Size Distribution on Sieve Trays in the Spray Regime

以空气／水为实验物系，应用双电子探针（ＴＰＳ）技术测定３００ｍｍ筛板塔上喷射工况下液滴粒度的分布，获得了液滴数量分布密度及体积分布密度随其粒度变化的实验数据．用此数据对比检验已提出的正态、对数正态、上限对数正态及ＲｏｓｉｎＲａｍｍｌｅｒ（简称ＲＲ）４种分布函数，从而验证了ＲＲ分布函数的适用性．对影响分布参数的因素进行考察，得出了分布参数随筛板孔气速及筛板上方位置高度变化的规律．

The two probe sensor method was used in determining the liquid droplet sizes on sieve trays in the spray regime.The results confirm that the function of Rosin Rammler is better than that of normal, log normal and upper limit lognormal in discribing the droplet size distribution.The factors which affect the distribution parameters were given.
