eng Abstract:
The aim of this work is to broaden the knowledge of the hydrodynamic interactions that occur between bubbles and solids of a comparable size. Focusing on collision processes between a single rising bubble with mobile surface and a larger falling solid spherical particle in stagnant liquid, the theoretical model describing the bubble trajectory is given here. The model is based on forces acting on the bubble and utilizes also equation for the bubble motion. The bubble is considered to be spherical and its motion is straight and rectilinear. The particle is spherical and moves vertically down with a steady velocity; the flow around the particle is axially symmetric.
