Abstract: On the basis of combination of droplet population,by taking the initial location as marginal distribution,the velocity and the diameter as conditional ones, a probability model describing the motion characteristics of droplets in cross rotating packed bed was proposed,and a three dimensional droplet motion model was developed. The calculated result from the model was verified by experimental measurements.

摘要： 首次从气体的流场、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，提出了错流型超重力旋转填料床中液滴的运动模型.采用四阶Runge-Kutta法计算，模型计算值与实测值吻合良好.
