When a bubble rises freely in still water, it often moves along zigzag or spiral trajectory. In order to explore the mechanism of this movement, an experiment was conducted record changes movement trajectory and shape. The results show that can be explained by swing trailing vortices change vorticity. There is asymmetric shedding vortices. velocity caused will lead vorticity Two factors drag fo...

A new Boundary Element Method software for simulating bubble dynamics is presented. This tool allows us to simulate a wide variety of scenarios, including external acoustic fields and multiple bubble interaction. We present results on the interaction between two oscillating bubbles in various configurations. Different sized bubbles under the effects of acoustic fields at different frequencies h...
