Nettet3. jul. 2024 · Schematic diagram of hollow fiber Full size image In practical applications, the length of the membrane was around 1.5 m and the inside radius is about 0.4 mm, and thus the aspect ratio ( ri / L) of the studied model < < 1. NettetWhen scaling up (or scaling down) a process for a hollow fiber cartridge you must preserve the flow geometry by keeping the fiber length and the lumen diameter the same for the scaled cartridges. For example, a 30 cm Xampler (UFP-x-C-3MA) will scale up to a size 35 (UFP-x-C-35) since both cartridges have the same fiber lumen ID(C=0.5mm) …

The same approach can be used to prove the other observations.

NettetWhat is claimed is: 1. A process of making a reinforced hollow fiber membrane, the process comprising: applying reinforcing filaments to a core while moving the core longitudinally; casting a dope over the reinforcing filaments and the core; forming a membrane from the dope; removing the core; and shrinking the reinforcing filaments … Nettet7. nov. 2024 · The trend applies to all investigated air gap. Li et al. reported similarly for PEI hollow fiber membrane. The lumen diameter enlarged to maintain the bore fluid velocity during the extrusion (Le et al. 2024). According to the author, the fiber expanded at a high flow rate and reduced the possibility of lumen deformation.

NettetThe collapse of the hollow fiber membrane would then constrict the membrane lumen, limiting the passage of gas from the membrane into the bubbling soup setup and resulting in low permeation reading. Since lumen constriction was more severe at higher pressure, the sample exhibited lower permeance at 5 bar than at 4 bar.
