This is a computational fluid dynamics simulation...to my knowledge, 
nobody has done one with the ability to output to POV-Ray. Graphics 
packages usually use particle systems for this sort of thing, which can 
give convincing results, though not as accurate as this algorithm. There 
are particle systems which include object interaction, your best bet is 
to try one of those.

  Are you sure the sample scene is making flow calculations to get the
effect or just faking the effect with clever placement of objects?

If you have some idea please tell me: in the other hand I will try to
produce this effect with huge number od particles.
