Research on rheological behavior in slurry pipeling transportation

Rheological behavior is an important parameter in the slurry pipeline transportation, it has a direct impact for the resistance loss and critical velocity on pipeline. It is extremely important to exact test and calculation the rheological parameters. Virtual rheological equations deduced based on slurry rheological model and motion model; measured using a capillary viscometer side wall of a pulp sample average shear stress and shear rate; calculate the real test of the slurry rheological parameters. Characterization of the shear rate diagram showed shear resistance of the main reasons for the particle collision, friction and structural characteristics of fine particles. Tests showed that the pseudo-shear diagram method can be more accurately measured slurry pipeline transportation rheological parameters, it is for engineering and scientific applications have some guidance.
