And I don't know how to make bubbles inside main fluid. Some one help me, Thanks so much.

That is a good question.

I suspect it starts with a second emitter and having the particles mixed in together as they flow. Obviously, there would be fewer of the "air" particles. When its time to create the mesh, only generate geometry for the "fluid" particles, which will leave a gap anywhere an "air" particle is occupying a space.

There's probably many more details that would have to be worked out, but that's a place to start.

Good Luck,

Other methods include a "filter" daemon where you transfer particles to a container emitter depending on speed, vorticity or collision with an object. Then, the container emitter will show particles that have higher surface tension, different densities etc. and you could attach a gravity daemon that moves them upward and a drag daemon with shield effect turned on, both acting only on the bubble particles.

Again other methods involve scripting where you convert particles of the water emitter into bubble or foam particles.

I've found a new solution for it. I get particle from DY_Domain to HY_Domain, after that add bubble for HY_Domian. So, the first step is ok. I will update video soon.
