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.
