| 摘要: |
| 基于一套冷模填料塔晃动试验装置研究海上晃动工况对填料塔流体分布性能的影响。根据横摇、纵摇、横荡、纵荡、垂荡、艏摇6个单自由度晃动试验结果,分析筛选出对流体分布性能影响较大的晃动形式。以此为基础两两相互耦合得到两自由度耦合晃动工况。再通过分析塔出口截面处的整体流量分布、环形流量分布、径向流量分布、壁流量分布试验指标,得出两自由度耦合晃动条件下填料塔流体分布规律。结果表明,摇摆及摇摆+摇摆的耦合晃动工况对液体的流动性能影响较大,并且随着晃动幅度增加,流体不均匀性增大。平荡对于液体流动性能的影响较小。 |

| Abstract: |
| In a sloshing experimental facility of packed tower, the fluid distribution performance of packed tower under coupling sloshing conditions was studied. The sloshing patterns which have a great influence on the fluid distribution performance were analyzed and selected through six single degrees of freedom sloshing experiments. Then, the selected sloshing patterns with single degrees of freedom were combined in pairs to get the coupling sloshing patterns. The fluid distribution performances of packed tower under the coupling sloshing conditions were obtained by analyzing the overall flow, annular flow, radial flow, wall flow in the exit area of packed tower. The results show that swaying and swaying+swaying coupling sloshing working condition have a large influence on the fluid distribution performance, and the flow unevenness is increasing accordingly with the increase of sloshing strength. Flat swing has less effects on the fluid distribution performance. |
