Development and characterization of transparent slurries for basic and applied research in solids transport
Conference

OSTI ID:5695674
This paper discusses some of the problems associated with refractive index matching of solids to produce transparent slurries that have rheological properties (including wall-slip and a yield value) similar to commercially important slurries. The recent development of these transparent slurries has made it possible to use laser Doppler velocimetry (LDV) to characterize the velocity profiles and rms components of velocity of non-Newtonian slurries in laminar, transitional, and turbulent flows. Rheological properties of the transparent slurries, measured with a concentric cylinder viscometer, are compared to rheological properties determined from pressure gradients and flow rates in large-scale pipe flow. LDV measurements of the laminar and turbulent velocity profiles will also be discussed. 15 figs.
