Bubble-Bubble Interaction:

I have recently initiated an investigation of the interacting bubbles. This was a natural extension of my previous work on the drop-drop interaction. I believe with my insight into the drop-drop interaction I could contribute to the problem of bubble-bubble interaction. This proved to be a fruitful investigation, since we discovered certain physical phenomena that were never before reported.  In my recent JFM paper in this area, I have shown that two bubbles may attract or repel each other under certain conditions, or may have a stable oscillatory behavior.  I am currently extending this work to multi-bubble interaction. This work was supported by NASA micro-gravity program. The objective of this work was to find a technique to separate bubbles from melts, which is a problem in the crystal growth in the microgravity environment.
