【 摘 要 】

References(24)Cited-By(9)Filtration characteristics of power-law non-Newtonian fluids–solids mixtures are investigated by use of a specially designed filter having a hole at the top of the filter chamber. On the basis of the principle of sudden reduction in filtrationarea of the cake surface, a method is developed for determining such overall filtration characteristics as the ratio m of wet to dry cake mass and the average specific filtration resistance γav for power-law fluids. Analytical equations are derived for correlating the overall filtration characteristics with the point or local values in filter cake. The compression-permeability characteristics, which are essential to the theoretical analysis of the mechanism of filtration within compressible filter cake, are evaluated on the basis of the overall filtration characteristics obtained under various filtration pressure conditions. It is shown that the results obtained from the newly developed non-Newtonian filtration technique are in good agreement with those obtained from conventional C-P (compression-permeability) cell measurements and Newtonian filtration experiments.
