The bubbles I see are around 2 or 3 maybe 4 mm in dia and i presume this will cause some circulation as they rise. Difficult to estimate I presume.
I still think the surface will have some deformation due to the bubbles presence and also the surface tension. Again hard to estimate or model but...
Kashishi I think we are talking about bubbles on the surface and not rising up in the fluid, that would be a very different scenario I think. Also way more complex with buoyancy, motion, viscosity etc so it is just the simpler case of the surface.
I recommend a glass of gin and tonic and just...
Thanks A T
I kinda thought as much but when they sit on the surface they only get attracted when the 2 bubbles are within the 8 times diameter of each other so is there some limit to how far the surface tension acts. I would have thought that the surface tension was like a field that diminishes...
I noticed whilst watching the tiny bubbles rising up in a glass of tonic that if they are close enough to each other they come together and coalesce. I tried to note the distance and my best guess was that at 8 times the bubble diameter the bubble attracts others. Sometimes they get attracted...
