Hydrodynamic interaction among multiple spherical particles

Prahl Wittberg, Lisa ; Revstedt, Johan LU and Lundell, Fredrik (2010) 7th International Conference on Multiphase Flow
Abstract
Multiple sphere formations are studied for Reynolds numbers of 100 − 300 in order to better understand the hydrodyanmical interaction among spheres. Spheres placed in tandem, diagonal as well as cluster formations including 3–5 spheres are investigated using a conventional finite difference method where the Volume of Solid (VOS) method is used to represent the spherical particles. The results show that, independent of sphere formation, an overall trend is that the front spheres are the least affected by the inclusion of additional spheres in the formation. Although sphere characteristics depending on position within a formation is found, the behavior of the trailing spheres changes with formation type, number of spheres, separation... (More)
