Computer-generated packing

The approaches to computer-generated packings have been classified into two main classes (Liu and Thompson, 2000) sequential deposition (SD) and collective rearrangement (CR). Typical of SD are the drop-and-roll algorithms, in which particles are added one by one to the packing and allowed to move until they find a gravitationally stable position. These algorithms usually result... 

Barnard Chemical Information—provides chemical Fingerprint Generation Pack— to compute fragment-based fingerprints for cluster and diversity analysis (113)... 

What can now be accomplished rather easily is the computer generation of many (a great many) crystal structures and the calculation of the packing energy and external vibrational entropy of each of them. In such an approach, only empirical potential energy schemes can be applied, due to the huge... 

In order to understand the nature and mechanisms of foam flow in the reservoir, some investigators have examined the generation of foam in glass bead packs (12). Porous micromodels have also been used to represent actual porous rock in which the flow behavior of bubble-films or lamellae have been observed (13,14). Furthermore, since foaming agents often exhibit pseudo-plastic behavior in a flow situation, the flow of non-Newtonian fluid in porous media has been examined from a mathematical standpoint. However, representation of such flow in mathematical models has been reported to be still inadequate (15). Theoretical approaches, with the goal of computing the mobility of foam in a porous medium modelled by a bead or sand pack, have been attempted as well (16,17).
