An investigation of sphere packed shell-side columns using a digital packing algorithm

Digital predictions of complex cylinder packed columns

“…Figure 4 illustrates that for this triangular shell-side bed arrangement at least, smaller cylindrical particles result in an overall lower radial voidage. This demonstrates that smaller particles, as with spheres (Caulkin et al, 2007), form a more compact packing within shell-side beds than larger particles.…”

“…The underlying principle of the method is digitisation of the particles and packing space, enabling the generation of realistic structures. Previous publications (Caulkin et al, 2006(Caulkin et al, , 2007 have demonstrated the ability of the code in predicting the packing of spheres. For cylindrical particles, however, the original, random walk-based code proved less effective at predicting bed structure.…”

Validation of a stochastic digital packing algorithm for porosity prediction in fluvial gravel deposits

“…These advantages make it attractive to create packings of complex fluvial deposits, and to study the grain shape effects on porosity. Applications of this stochastic digital packing algorithm have proven to provide relatively accurate porosity predictions for both fine powders and large spheres (Caulkin et al, 2006(Caulkin et al, , 2007 in the fields of material science and engineering chemistry. Nevertheless, the packing algorithm has not yet been used for generating packings of fluvial deposits.…”

One-dimensional isothermal multicomponent diffusion-reaction model and its application to methanol synthesis over commercial Cu-based catalyst

“…Methanol has many great advantages in properties and its practical application as an alternative fuel 1 . Large scale methanol synthesis is the trend of the methanol industry in the world and corresponding methanol synthesis reactor technology is necessary for large scale methanol production 2, 3 .…”
