Paper presented at the 9th International Conference on Heat Transfer, Fluid Mechanics and Thermodynamics, Malta, 16-18 July, 2012.
In the paper the dynamics of liquid movement inside the glass nozzle submerged in the glass tank filled by distilled water has been analyzed. Considered liquid movement accompanied the process of bubble departures from the nozzle. There has been investigated the influence of air volume flow rate on the dynamics of liquid movement. The position of liquid-air interface inside the glass nozzle has been measured using the high speed camera. Recorded videos have been analyzed using the special software allowing to obtain the time series of position of air-liquid interface inside the glass nozzle. The dynamics of such obtained time series has been analyzed using the non-linear methods. The attractor reconstruction, correlation dimension and reoccurrence plot have been applied.
