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 . 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 the droplets in the 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.
