文摘
- •
Computational fluid dynamics (CFD) used to examine flow in twisted fibers.
- •
Secondary flows lead to high vorticity and wall shear rates.
- •
Azimuthally-averaged normal velocities much greater than filtrate flux.
- •
Magnitude of secondary flow similar to that in helically-coiled fibers.
- •
Results demonstrate enhanced mass transfer in easily scalable modules.
