Friction losses for flow of concentrated slurries.
Author(s) : STUTZ B., REGHEM P., MARTINEZ O.
Summary
The experimental tests are carried out using a slurry flow facility with polypropylene particles, consisting of a flow loop though which the different piping elements are installed. Friction losses in horizontal pipes, bends, contractions, and enlargements have been measured. The pressure drops depend strongly on the flow pattern. For suspended particles regimes, the Blasius law based on Reynolds numbers defined from water viscosity and mixture density, is appropriate. Inversely, for moving bed regimes, pressure losses depend on the concentration of the solid phase. Two models of pressure losses in pipes have been developed. The first one is a correlation, the second one uses the Bingham fluid to model the flow. An extended Reynolds number is introduced. The Blasius law computed with the extended Reynolds number is found to be applicable in its full range.
