Flow Visualization of Liquid Crystalline Polymer Solutions in Rectangular Channels
Velocity profiles of aqueous solutions of Hydroxypropylcellulose flowing in rectangular channels were visualized by means of an electrochemical technique. Isotropic and anisotropic solutions were used. The velocity profiles of the liquid crystalline solution were found to be qualitatively different from those of the isotropic one. In particular, anomalous maxima in the velocity near the side walls were observed.
