摘要:以轴向流吸附器内部流场为研究对象,采用CFD软件对其内部气体流动特性进行数值模拟.比较轴向流吸附器内无气体分布器、仅加装单一多孔板气体分布器、加装多孔板气体分布器与单级挡板相结合等3种方式对吸附器内部流场均匀分布的影响.未加装气体分布器的轴向流吸附器内部气流分布严重不均;仅加装单一多孔板气体分布器的轴向流吸附器内部流场的气体流动稍有改善,但气流分布仍不均匀;加装多孔板气体分布器与单级挡板相结合的方式,吸附器内部流场的气体流动得到明显改善.多孔板气体分布器与单级挡板组合使用时,保持气体分布器开孔率不变,开孔孔径为0.003 m时气流分布最为均匀,效果最好;保持开孔孔径不变,气体分布器的开孔率为0.388时气流分布最为均匀.
The internal flow characteristics of axial flow absorbers were numerically studied by the computational fluid dynamics( CFD) method. The influences of three absorber models on the internal flow uniformity were compared: absorber without a flow distributor,absorber with a single flow distributor,and absorber with the combination of a flow distributor and a baffle. The results show that the flow is severely uneven without a flow distributor,is slightly meliorated with a single flow distributor,and is significantly improved with the combination of a flow distributor and a baffle. For the combined configuration,the best flow uniformities are obtained with the pore diameter of 0. 003 m as the pore opening ratio remains unchanged and with the pore opening ratio of 0. 388 as the pore diameter does not change.
