You might want to think of it as whitewater. Use a particle system with gravity. When it comes render time, render the points using small spheres, then convert that to a volume and render them both. You'll get fog and polygon with that approach.

I vote for pyro sim for bulk with particles advected for details :D

ahah i think i would mix both approach describe previously.
- with only pop + gravity then vdb you will miss the swirly pattern of fluid 

- with a pyro sim + pop advect you will have hard time to get the simple direct gravity pattern

 

- i will start with a pop sims ( maybe pop grain to check if it bring something more granular ) to create the main gravity behavior

- then use that sim to emit vel + density in a whispy presets pyro grid

- then advect some additional pop in it that pyro grid that will fade fast 

 

and render :

- pop gravity + pop advected with high motion blur
- and whsipy fluid with low density shader
