Opis:
In this study the first part of the experimental data was recorded in a data acquisition station, and another one was recorded with a high speed camera. The data recorded using the acquisition station was recorded with higher frequency than the time between two subsequent frames of the film. During the analysis of the experimental data the problem was related to the synchronization of measurement from acquisition station and data recorded with a camera. In this paper the method of synchronization of experimental data has been shown. A laser- phototransistor system has been used. The data synchronization was required in scaling of sampling frequency in the investigated time series.

Opis:
The main aim of investigation was to analyze the influence of liquid movement inside the nozzle on the dynamics of bubble departure. Dynamics of such process decides about the periodic and aperiodic bubble departures. During the experiment it has been simultaneously recorded: changes of the depth of the nozzle penetration by liquid, air pressure and shape of bubble trajectory directly over the nozzle (in the length of 30 mm). The air volume flow rate was in the range 0.00632 - 0.0381 l/min. There has been shown that for all air volume flow rates the time periods with periodic and aperiodic bubble departures have been occurred. Duration of these intervals varies with the air volume flow rate. It has been found that the aperiodic bubble departures begin when the time of bubble growth increases. The changes of maximum values of liquid position inside the nozzle are associated with changes of the shape of bubble trajectories. There has been shown that straightens of the trajectory precedes the appearance of periodical or aperiodic time period of bubble departures. The aperiodic bubble departures are accompanied by a significant deviation of bubble trajectory from a straight line. The correlation dimension analysis shown that three independent variables are enough to describe the behaviour of liquid movement inside the nozzle. These independent variables may be: liquid velocity, liquid position in the nozzle and gas pressure in the nozzle.
