Oil and Steam FX

I am currently creating oil and steam fx. I am not really going for super realistic look, but more of an animated film style. I am using Maya fluids for all of them. I tried out nParticles for oil as well, but the results were not as nice and the "nParticles to polygons" conversion kept giving me problems.

1.) For the Steam FX , near the point of emission in the reference, there is a strong clean stream at the beginning. After the stream, the steam spreads/expands and swirl. The spread/expand part is the trickiest effect of the sim I am trying to get. So far the look seems more like particle clouds rather than a smoother fluid.

Here is the main reference I am using: link

2.) The Bubbling Oil test that is based on this boiling water tutorial:

I am trying to get bubble burst effects similar to the reference. Which particular settings should I focus on to get that effect? As seen in the playblast, part of the trouble is that the polygon spheres I am using as collisions also fill internally with fluid as they rise up. The result is not a natural bubble burst or one that does not allow the bounce to happen.

Bubbling oil reference: link

3.) For the Falling Oil , the main concern for the moment is the way the fluids interacting with the ground, as they are sliding around too much. The only solution I could find right now is viscosity, but that will also change the behavior too much as well. In addition, small bits of the fluid keep disappearing/reappearing.
