Spontaneous Bubble Production on the Needle
Vejražka, Jiří ; Zedníková, Mária ; Stanovský, Petr
The study of spontaneous bubble production on the needle is necessary to understand all possibilities to control the bubble production on the needle with desired volume and desired production frequency. For this reason the system, where the gas flows into the chamber and continues through the needle, is studied. This system is modeled using modified model of Oguze and Prosperetti (1993). The model results enable to understand how the chamber volume, the diameter and the length of the needle influence the forming process and size of the bubbles. The experimental results are also presented.
