Re: Has anybody studied the surface tension of smoke?

Hi Craig
           I have not really come across any study of the surface tension
of smoke itself. Smoke has been used to study surface tension in some cases
especially because it can mix gas flow very well.
Also smoke is defined as colloid, i.e. a suspension of nanometer sized
particles in a gaseous medium. SO you might want to expand your search to
"surface tension of colloids" and see if you get any relevant hits.


SOme links that I thought could help are:

Measurement of surface tension using particle image velocimetry

Further, surface tension is a microscopic but intensive property for a
given liquid or gas, but smoke is a collection of discrete particles in a
suspension so I think it might hard to "Define" surface tension of smoke,
You might call it, effect of smoke on the surface tension of the gas you
are looking at as the carrier.
This is of course my humble opinion and I might be only partially correct!
Good luck in your search!
