dc.description.abstract Director reorientation under pressure driven (Poiseuille) flow is observed conoscopically for the liquid crystal 5CB aligned at an azimuthal angle of 45° to the direction of flow. A polyimide surface treatment (AL 1254) is used to promote planar homogeneous alignment and rubbed to produce an initial azimuthal alignment angle Ø0. Conoscopic interference figure rotation is documented as a function of flow rate and compared to that produced from numerical models using Leslie–Ericksen–Parodi theory. Model and data show excellent agreement. en_GB
