This project involves the following "keywords": shear flow, particles, collisions, formation of agglomerates and collision efficiency.
We study a flow of fluid with particles in the following "cavity":
Where the upper and the lower walls are moving in the opposite directions, i.e. we have a sort of shear flow.
To make it more complicated: the particles are cohesive and to model their collisions + possible formation of agglomerates, we use a hard-sphere model that was extended to account for cohesion. This extended hard-sphere model is described in details in [1].
In this way we can investigate e.g. collision frequency (how often the particles collide), collision efficiency (how many agglomerates are formed as the particles are cohesive) etc.
Would you like to find out more about it? The results have been already published, see [2] (you can download the preprint).
