The Dynamic Shape Factors of Close Packed Agglomerates and Hollow Agglomerates.

The dynamic shape factors of two types of polyhedral shaped agglomerates were measured. One type consists of the close packing of 4 to 12 spheres.on a core sphere (close packed agglomerate, dynamic shape factor ks); the other has the same configuration as the above agglomerate except that the central sphere has been removed (hollow agglomerate, kv). The dynamic shape factor kvwas analyzed by using a model agglomerate in which the core void is simulated as a sphere of fluid (kf). Comparison of kv and kf shows that, for hollow agglomerates comprising a number of spheres between 5 and 13, part of the fluid flows through the core void.
