Helfrich’s model of permeation

Fig. 4.5.4. Helfrich s model of permeation in a cholesteric liquid crystal. At low shear rates flow takes place along the helical axis without the helical structure itself...

Fig. 5.3.8. Helfrich s model of permeation in smectic liquid crystals. The flow takes place normal to the layers in a manner similar to the drift of charge carriers in the hopping model for electrical conduction.
