Particle packing structure dense random

Figure 8. The calculated relative viscosity is plotted against particle volume fraction using Eq. (39). A dense random packing structure is assumed and ( )n,=0.63. K-D represents Kreiger-Dougherty, and F-A the Frankel-Acrivos equation.

The above factors are well explained by Maiti et al. Under the structure of the packed bed, the liquid distribution is dependent on 1) porosity distribution 2) Z)/dp ratio D is the diameter of reactor and dp is the equivalent particle diameter) 3) H/d ratio (orientation problem) H is the height of the catalyst bed) and 4) method of loading—convex, concave, and random (sock and dense loading).
