Notes:
A new apparatus to investigate the structure of fluids under Poiseuille shear flow using small-angle neutron or light scattering techniques is described. Important features of the design include low sample volumes, area average shear rates of up to 5000 s−1, accurate temperature control over the range of 10–125 °C, and the ability to study the development of flow-induced alignment phenomena. Small-angle neutron scattering data are presented for two example systems: the well-characterized surfactant system C16E6/D2O, used to contrast the effects of Poiseuille and Couette flow, and the block copolymer Synperonic P-85/D2O system. © 1996 American Institute of Physics.
