Dynamic Shape Factors of Regular Shaped Agglomerates and Estimation Based on Agglomerate Symmetry – For Rectangular parallelepiped, V-and W-shaped, Hexagonal and H-shaped Agglomerates – [Translated]<sup>†</sup>

Abstract

Dynamic shape factors for regular-shaped agglomerates, such as rectangular parallelepipeds, V- and W-shapes, and others, have been calculated from their measured terminal settling velocities in the Stokes regime. Experimental results have been analyzed by using a new correlation based on two-sphere hydrodynamic resistance as presented in a previous work. Estimated and experimental dynamic shape factors are in good agreement, with deviation smaller than 5%. The correlation can estimate the dynamic shape factor of a double-sized symmetrical agglomerate from its components, and also in a direction with an unstable settling orientation.† This report was originally printed in Kagaku Kogaku Ronbunshu, 22(1), 98-105 (1996) in Japanese, before being translated into English by KONA Editorial Committee with the permission of the editorial committee of the Soc.
