JOURNAL FREE ACCESSThe property of a shaped body by slip casting in ceramic processing greatly depends on the dispersive state in the slurry.
The agglomerate process in a high densed slurry we studied by three dimensional computer simulation. The movement of particles was determined by cohesion probability between particles. The aggregative state and this process was discussed from the view points of the aggregation rate, the coordination number and the aggregative ratio by using cohesion probability.
The experimental results from the measurement of viscosity and SEM observational dried slurries supported this simulation well.View full abstractDownload PDF (2161K) -
Effects of Air Flow Rate and Blade Attitude Angle on Cut SizeYuichi SATO, Takuo NAGAMINE, Yukiyoshi YAMADA1990 Volume 27 Issue 4 Pages 225-230

JOURNAL FREE ACCESSThe trajectories of particles thrown into a forced vortex type centrifugal air classifier are calculated numerically. The effects of the air flow rate and the blade attitude angle on the cut size are verified. The cut size is determined by the blade attitude angle as well as by the radial air flow rate. The lowest cut size can be reduced by increasing the blade attitude angle.View full abstractDownload PDF (742K) -
Effect of Resistance Ratio of Two CompornentsKiyoaki KOMATSUZAKI, Kunihiko NAKASHIMA, Toshimi WATANABE, Atsushi YOS ...1990 Volume 27 Issue 4 Pages 231-235

JOURNAL FREE ACCESSIn the previous paper, the total electric resistance of a planer binary system of particles was studied from the viewpoint of the combinatorial theory, and it was concluded that the electric path (or percolation path) of the system could be made under a certain condition of the RK-RS relationsihp. (RK: Total electric resistance of the system calculated by applying Kirchfoff's law, RS: Total electric resistance of the system calculated by series-and-parallel method). In the present paper, the problem of the percolation phenomenon of the system was studied in detail. The details of the condition whereby the geometry of the electric path might be governed was referred to. Furthermore, the percolation probabilities(P(p)) of the system which were determined by counting up the number of RK-RS plots in percolation region and non-percolation region were referred to.View full abstractDownload PDF (590K) -
