Although many researchers have investigated the rheology of gas-fluidized powders no reliable theoretical description is as yet available. Various measuring methods have been applied, varying from Stormer, Brookfield or Couette viscometers, torsion pendulum or floating/falling ball-methods to the study of average flow velocity through open inclined or ...

Characterization of impregnated particles via powder rheology
Powder Technology, 2009This work presents a specific application of a new powder rheometer prototype, for the characterization of liquid-impregnated particles which are used in chemical engineering for gas treatment on fixed beds. This new type of rheological characterization can provide useful information about the surface state of the particles and could contribute to the ...

Journal of The American Ceramic Society
We investigate the rheological properties of ceramic slurries designed for laser stereolithography manufacturing in relation to their formulation, including the powder morphology, their volume fraction, and the concentration of dispersing agent.

The Rheology and Hydrodynamics of Dry Powder Lubrication
Tribology Transactions, 1991This paper conceptualizes a powder lubrication mechanisms which closely resembles that of a hydrodynamic fluid film. Based on the observations of past investigations and on the author's experiments, it is postulated that a layered shearing of the compacted powder generates velocity, density, and temperature profiles akin to fluid film bearings. Thus, a

The Role of Water in the Rheology of Hygroscopic Food Powders
1985The effects of water activity on the biochemical and biological stability of foods have been extensively studied and the results of these investigations can serve as useful guide-lines in processing and storage (7, 25, 27). The effects of water on the physical stability of dry foods have also received considerable attention, especially in sugar rich ...

Adsorption, rheology, packing, and sintering of nanosize ceramic powders
Ceramics International, 1999Abstract Nanosize zirconia particles stabilised with a water-soluble polyelectrolyte in an aqueous medium were characterised in terms of adsorption behaviour, suspension rheology, and subsequent green/sintered compact microstructure. A monolayer surface coverage of the particle by adsorption was experimentally verified.
