as a stand in smoke you can use particles and color the particlecloud shader...

the trick is how much particles you need and tweaking the fields that you use to make your smoke roll.... for this its a combination of using your turbulence, volume axis(or uniform) and maybe a little bit of a radial field.... its all trial and error basically when it comes to tweaking them....

You'll probably have to use a few particle systems to get this look also, without fluids you can get close to what fluids can produce...
