Hi there.
It would be nice to see a Loop subdivision surface implementation. And, may be, some other subdivision algorithm too.
But, especially desirable would be the "Quad/Triangle Subdivision", such as described here.

My experimentation continues, so I have a few new pictures:

The speed is greatly improved and the algorithm is greatly simplified, but still has some problems. I'll working on it.

Interesting, care to elaborate on the process? Are you just evolving the field a number of steps equal to the frame number?

I would guess that the dissipation is coming from the fact the density output isn't coupled with the evolving vel field, so you lose the divergence-free projection. You see the same effect when advecting particles through a field over a long period of time.
Another pictures, from another algorithm, not so good for now, but (I hope) can be improved...
