TurbulenceFD : Spiral smoke ?

[omegear]

Hello everyone,
I'm looking to recreate the kind of spiraled clouds/nebula from this




But no matter what I try, the TurbulenceFD smoke always goes up. I tried some modification in the simulation tab, like wind but it just go in one direction with the wind modifier.
I then tried to rotate xparticles and emit smoke from them, but still the same issue (it's not an issue per say but I can't find what need to be done to have this kind of spiraled fog/smoke) :


I'm not usually asking for help but this is crucial to my knowledge, is it even possible to do it with TurbulenceFD + xParticles ?

Thank you !

May be you could have a ring selection from the sphere emitt a few particles while having the sphere turning, and then have those few emitted particles emitt some more particles themselves around them.
Apparently in the next xparticles you’ll also be able to emitt from splines … but i guess this is more a question from an xparticle generating point of view, than from an octane render point of view …
