| 摘 要： | 采用粒子图像成像技术（PIV）测定了旋转床空腔区内液滴尺寸和液体的流动速度，研究了填料厚度和转速对空腔区内液滴平均直径的影响，得到的液滴平均直径范围为0.15~0.9 mm。利用粒子图像成像技术观测了空腔区内流体流动情况，验证了旋转床内径处存在流动端效应区。对测量得到的速度进行了关联，得到了旋转床空腔区内液滴速度的关联式。最后通过引入切向相对速度差σ，得到了设计中所需最小填料径向厚度为10cm。

| Abstract: | Particle image velocimetry(PIV) has been used to measure the size of droplets and velocity of flowing liquid in the cavity region of a rotating packed bed(RPB).The effects of varying the operational conditions(thickness of packing and rotation speed) on the results were investigated.The average droplet diameter was found to be in the range 0.15-0.9mm.The results confirm the presence of a fluid end effect region in the interior of the packing.A velocity correlation was modeled in the RPB based on the experim... |
