Bubble-particle collision interaction in flotation systems
Original language description
tThis work studies single bubble-single particle interactions of interest to flotation applications. An exper-imental device has been developed where a standing bubble is approached at prescribed flow velocityby an aqueous dispersion of particles - muchsmaller than the bubble. Two separate high-speed cam-eras are employed to monitor the bubble surface from two different Cartesian directions allowing thusa 3D perspective of particles trajectories and collisions with the bubble. A special feature of thedevice isthat the velocity of the suspension and the size of the bubble can be independently adjusted in a rangeof values that corresponds to the flotation process. This paper presents experimental trajectories andvelocities of particles as they approachand flow past a bubble. A theoretical model has been developedto describe such particle trajectories and velocities. Comparison between experimental observations withmodel predictions allows a detailed assessment of governing forces and
