错流型超重力旋转床中液滴的运动及二维建模

A Two-Dimension-Motion Model of Droplet in Cross-flow Rotating Packed Bed

从气体的流场和液滴的碰合出发 ,用液滴粒径 -位置联合分布模型描述了液滴群运动的特征 ;在此基础上 ,提出了错流型超重力旋转填料床中液滴的二维运动模型 .模型物理意义明确 ,不含有可调动参数 .模型计算得到的液滴的相界面积与实验实测值的误差在 10 %以内 .

A two_dimension_motion model is proposed to describe the motion and combination of droplets in the cross_rotating packed bed. The calculation was based on the experimental data. The error for calculating the interface area of the droplets by using this model is within 10%.
