Abstract
Optical Coherence Tomography (OCT) has opened whole new
possibilities for measuring boundary layer properties for
opaque fluids. Our results clearly demonstrate the
benefits of having direct measurement of the velocity
field inside the rheometer instead of using assumed
velocity profile as the basis of interpreting the
measured rheometric data. OCT has the potential of
significant breakthrough in understanding the rheological
properties of complex opaque fluids such as MFC. By
utilizing this method we have obtained new information
about flow instabilities inside a rheometer gap and used
this data to interpret rheometer flow curve.
