Annuli have been built with longitudinal grooves or splines on both inner and outer tube surfaces, using microporous teflon tubing with appropriate extruded cross-sections. Axial twisting of the tubes (which makes the splines helical) gave enhanced mass transfer, counter-twisting being more effective than co-twisting.
