Characterization of multiphase fluid flow during air-sparged hydrocyclone flotation by x-ray CT. Fourteenth quarterly report, 14 November 1993--13 February 1994

摘要

During this quarter of the DOE project, ''Characterization of Multiphase Fluid Flow During Air-Sparged Hydrocyclone Flotation'', efforts were made to correlate the x-ray CT measurements with the flotation experiments reported in the last. quarterly report. In this regard the axial view of the flow regimes in the ASH during steady state operation were constructed from the radial density profiles as revealed by x-ray CT measurements. By studying the characteristics of the flow regimes from these axial views and relating them with flotation recovery data, a more detailed understanding of ASH flotation was possible. Construction of the axial view of the flow regimes and the effect of two operating variables, dimensionless area ratio (A* = overflow opening area/underflow opening area) and percent solids in the feed, are reported in this quarterly report.
