Flow loop study of a cold and cohesive slurry. Pressure drop and formation of plugs

Slurries of cohesive particles constitute a significant risk during subsea petroleum production due to their potential plug the flow. This article describes flow loop study slurry consistent with 0.23-mm ice in decane. The experiments were conducted for concentration up 20.3% vol. and Re < 25000. cohesion was suggested by controlling temperature slurry. relative viscosity computed as function particle using pressure drop measurements. 3.1 20.3%. Bingham-fluid model agreed empirical calculations within discrepancy 15.5%. Increased led higher compared single-phase case. Pressure drops 5.2% 44.4% than pure decane at Reynolds numbers 24778 4956, respectively. test section equipped an orifice induce formation plugs. plugs observed concentrations below 7.0%. presents detailed experimental logs depicting process formation. blocking cases partially maps from literature. In addition, we note applicability blockage evaluation technique Colorado School Mines.
