Abstract

Shear alignment in dispersions of kaolinite particles was measured using neutron diffraction. The orientation distribution of particles was determined as a function of flow rate. The plate normals move towards the shear gradient from the compressional direction as shear rate is increased from 0.2 to 20 s−1. The particle alignment also increases with flow. Order parameters are calculated and compared with theoretical models.
