Spray structure, OK, work on around 10 cells across the droplets. Then work back to get an idea of expected cell count. VOF to DPM may save you some cell count. 

The multiphase models were significantly upgraded in R17-R18 time frame, and we're now on 2024R2 (roughly 25.2 in old versioning). But may not give you the spray effect that you're after.
