This paper presents an approach to computing the sh ear flow curve from torque-rotational velocity data in a Couette rheometer. The approxima tion techniques in shear rate calculation are generally dictated by the radius ratio between coaxial cylinders and the rheological behaviour of fluid tested. Here, the approach consi sts in analysing the sheared material as a Bingham fluid and computing an average shear rate w h n the fluid in the cylindrical gap is partially and fully sheared. We focus… CONTINUE READING
