Abstract
Some aspects of the flow of colloidal crystals in a capillary are studied. Flow is induced in the shear region near where the crystal responds plastically by applying oscillatory pressure. Under certain conditions well oriented crystalline regions are observed which alternate orientations in a periodic pattern along the tube. Since the crystals have a lattice spacing of approximately 0. 5 mu and Bragg scatter visible light, a periodic color pattern is observed. The formation of these cylindrically symmetric striations is studied as a function of shear modulus, frequency and amplitude of oscillations, particle size and tube diameter.
