Rain drop simulation

alpharays · November 1, 2018, 01:59

Hi,

1) May I know which multiphase flow is suitable to simulate rain drop into a box?
My objective is to measure water volume in that box.

2) Which boundary condition should setup on the inlet? Is it mass flow rate, velocity or others?

Regards
Shah

For rain I would probably used the dispersed multiphase and the VOF model. That way you don't have to spend heavily tracking a ton of lagrangian particles.
