Thurgood, J R

Rheological characterisations were made for a coal liquefaction preheater slurry; measurements were made in line at high temperature and high pressure. Above 400 K, the coal-solvent slurry (35% wt. coal) was pseudoplastic and was adequately modelled by a power-law equation. Experimental data over a temperature range of 400-700 K were correlated, and critical slurry velocities for transition from laminar flow were calculated for flow in several pipe diameters.
