New flow regimes for propylene-glycol-based ice slurry in pipes.

Number: pap. 0016

Author(s) : BORDET A., PONCET S., POIRIER M., et al.

Summary

The objective of the present project is to analyze the flow regimes resulting from ice slurries flowing in a straight pipe using combined flow visualizations and pressure drop measurements. Ice slurry is composed of an initial solution of 9.5% weight propylene glycol. The influences of the inlet mean velocity and ice mass fraction on the flow patterns and pressure drops are characterized experimentally for ice concentrations up to 18.4% and for both laminar and turbulent flow regimes. A transition diagram has been established and new stratified regimes are identified compared to the existing literature.
