Abstract: Particles immersed in a fluid have always been an important researching domain in process technologies, pharmacy and fluid mechanics. It is for its practical utility in industry that the two-phase flow is still being academically researched, but in present times with a slightly different, more complex approach. Formerly all the particles have been assumed to be spheres, what simplified the models of processes physical presentation. Nowadays, however, it is clear that such an assumption makes significant errors in some fields of applications. With that reason ellipsoids were presented instead of spheres. That step also transferred computation from analytical or partially analytical to wholey numerical. This work presents the results of numerical simulation of different ellipsoids and sphere. In addition a Saffmann effect on sphere is presented as a special phenomena in fluid mechanics.Keywords: OpenFOAM, Saffman effect, drag coefficient, sphere drag, drag on ellipsoids, forces on immersed bodiesPublished in DKUM: 17.07.2017; Views: 932; Downloads: 135 Full text (2,30 MB)
