Fast Moving Steam

Recommended Posts

Hi! Does anyone have any tips for creating this kind of steam effect? 
 https://www.youtube.com/watch?v=LZYLoVCikqo&ab_channel=VeteransRailroad    (around the 0:20second mark) 

I'm trying to recreate super fast moving, high pressure steam coming out of a pipe about 0.5m in diameter. I've played around with sourcing a noised up density volume, custom vel to break up the shape, disturbance, a little divergence, turbulence and confinement ..etc. I'm using sparse pyro. Not sure if there is anything obvious I'm missing, will try to upload the file when I get home, but it seems like no matter what combination of sourcng and microsolvers I use I can't get past it looking like plumy-smoke as opposed to a fast moving stream with lots of small sharp details. I would really appreciate any tips! 

Thanks in advance!

You might not to simulate that at all? Just create a volume from a cone, add noise to the density, and animate the offset of the noise?

Thanks for the tip Atom, that's a really good idea. I need to add collision behavior with some things in the scene though so I do think I'll need to sim it

One parameter you can play with, which drastically reduces the initial mushrooming effect, is Cooling Rate. Try setting it to 1.0.

Very cool, thanks Atom. I had bumped it up a bit but definitely having it all the way up at 1 makes it look a lot better. Really appreciate the help!
