DYNAMIC SHAPE FACTORS OF REGULAR SHAPED A GGLOMERATES AND ESTIMATION BASED ON AGGLOMERATE SYMMETRY - FOR RECTANGULAR PARALLELEPIPED, V-SHAPED AND W-SHAPED, HEXAGONAL AND H-SHAPED AGGLOMERATES

Dynamic shape factors for regular shaped agglomerates, such as rectang ular parallelepiped, 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 b ased on a two-sphere hydrodynamic resistance; presented in a previous work. The estimated and experimental dynamic shape factors are in good agreement, with deviation smaller than 5%. The correlation anablesest imation of the dynamic shape factor of a doublesized symmetrical agglo merate from its components, and also in a direction with an unstable s ettling orientation
