Individual bubble-particle collisions were studied using a high speed video recorder. An algorithm for determining a particle’s trajectory in three-dimensional space during a collision with an air bubble through a frame by frame analysis of the recorded video sequence is described. Evidence that the moment of bubble-particle attachment can be detected from the particle trajectory is examined.
