Abstract
In this work a novel laboratory-scale pipe rheometer is utilized in
rheological characterization of concentrated MFC and cellulose suspension. The
method is based on a combination of pulsed ultrasound velocity profiling
(UVP) and pressure difference measurement (PD). The rheological properties of
the suspensions are described in terms of viscosity and pressure loss. The
resluts are compared to rotational rheometer results. It is demonstrated that
well controlled pipe flow environment together with UVP-PD technique is
efficient in characterizing the rheological flow behavior of complex slurries.
