Extending acoustic in‐line pipe rheometry and friction factor modeling to low‐Reynolds‐number, non‐Newtonian slurries

The rheology of non‐Newtonian slurries is measured in a recirculating pipe loop using an acoustic velocimetry‐pressure drop technique at very low flow rates and variable solids loadings. The technique avoids (a) settling at low solids concentration, a shortcoming of bench rheometry, by using a verti...
