You want water and particle effect analogues rather than direct CFD calculations which are far too computationally expensive. i.e. you want this (probably even more simplified): https://matthias-research.github.io/pages/publications/sca03.pdf https://matthias-research.github.io/pages/publications/sca03... and not this (used for accurate real world simulation of fluid physics): https://en.wikipedia.org/wiki/Reynolds-averaged_Navier%E2%80%93Stokes_equations https://en.wikipedia.org/wiki/Reynolds-averaged_Navier%E2%80...
