Abstract
In the paper, nonlinear features of the air bubbling from a submerged glass nozzles are discussed. The air bubbles were emitted from glass nozzles of different diameters submerged in distilled water at a depth of 15 cm in a cylindrical tank of 30 cm in diameter and 37 cm height. The air volume flow rate was changed from 1 l/h to 45 l/h. A laser-photodiode and an acoustic technique system have been used. Also photographic study of bubbles departure has been carried out. Measured data have been analysed using the fractal analysis method. It has been shown that bubbles dynamics is of deterministic chaos nature and behaviours of such system can be chaotic or periodic depending on the volume flow rate. The map of chaos appearance has been constructed. Data recorded by acoustic system has been used to analysis of bubble wall movement.
