ON INTERACTIONS OF STATIONARY PARTICLES AND RISING BUBBLES

Popis výsledku v původním jazyce

The goal of this project is to broaden our knowledge about hydrodynamic interactions between bubbles and solids of comparable size that occur in the flotation process. We studied the collision process between a single rising bubble and stationary spherical particle. The experimental research was focused on the description of a bubble trajectory, collision efficiency and the determination of the limit collision angle. According to the obtained results, the trajectory deviation caused by the presence of astationary solid spherical particle is very small. No collision occurs for initial angles greater than 75°. A good starting point for theoretical description of interaction between a small bubble and a large particle is the study of a bubble collision with an inclined plane, representing a particle of infinite size. The model theory was created for this type of interaction. The bubble trajectory before and during the interaction with the inclined plane was calculated and compared with e
