Topic :
The PhD work is dealing with the experimental study of bubble induced microstreaming. This includes the study of nonlinear time-resolved bubble dynamics of single bubbles as well the triggering of surface modes by coalescing bubbles. Experimental methods contain the bubble nucleation by focused laser, its control in the acoustic field, its observation by high speed camera and the visualization of the surrounding flow by particle image velocimetry. Validation is achieved by comparison with analytical models.

The mayor steps are

  • bubble coalescence as a means to control the bubble dynamics

  • microstreaming and its correlation to bubble dynamics
