Modeling Splashing with DPM-Urgent!

Arash

I want to model the splatter of droplets in a flow around a blunt body using wall-film boundary condition for the body surface. I have solved the flow around the body using RSM and now want to inject droplets upstream the body and see the trajectories after droplets impact and break into new droplets.

But when I track the droplets, the result is like rebounce of drops from the surface, which is not expected at this velocity and temperature conditions. I read something in Fluent manual about using compressible flow for such a case. Do I really have to solve the flow as a compresible one?

Does anybode have any similar experience?

Thanks, Arash
