Help Is it possible to simulate a fine spray effect like a shower head?

[twocomet]

I'm currently trying to achieve a fine spray effect similar to a shower head using Obi Fluid.
I've experimented with adjusting the Water blueprint, but I haven’t been able to replicate the shower head spray properly.
I also tried using multiple small nozzle holes by placing several emitters close together, but the emitted fluid particles tend to merge together right after spawning, which ruins the fine spray effect I'm aiming for.
Is there a method or setup that could help simulate this kind of effect more accurately?
Any tips or mechanisms that could prevent the particles from merging too quickly would be greatly appreciated.

Fine spray is made of extremely small particles. Physically simulating this is rather wasteful, as drops tend to move independently from each other: no noticeable pressure, surface tension, viscosity, vorticity, or any other effect is visible. Visuals-wise, reflection, refraction and absorption are barely noticeable since you usually can't stop and look at each individual drop up close. So imho, using a regular particle system is simpler, will run a lot faster, and look a lot better.

While it can be done using ObiFluid, it will require extremely small particles and very fine voxel size for meshing, making it a highly impractical approach.

I've experimented with adjusting the Water blueprint, but I haven’t been able to replicate the shower head spray properly.

Set the blueprint's resolution very high (exact values depend on your scene scale, but aim between 15 and 30, you're currently using 2 which will yield very large particles). Also set polarity to zero, to ensure particles do not attract each other but stay separate. Then set the fluid mesher's voxel size rather small, around double the size of a single particle.

I also tried using multiple small nozzle holes by placing several emitters close together, but the emitted fluid particles tend to merge together right after spawning, which ruins the fine spray effect I'm aiming for.

Your polarity is set to 1 (100%). This will make particles strongly attract each other giving rise to large surface tension which you certainly don't want in this case. Also and the voxel size of your fluid mesher its way too large, judging from the screenshots.

kind regards,
