Hello cfd - online community,

I am currently using Ansys Fluent to model film formation on a rotating milling tool. The liquid film is formed when droplets from an atomization unit strikes the rotating tool. I know how to prescribe a rotational velocity to a cylinder but when the geometry is that of a milling tool, I don't know how to prescribe a rotational velocity. Initially I thought of using the Single rotating reference frame, however as I have to model the liquid spray coming out of the atomization unit as well, I am not sure if I can use the single rotating reference frame.

I would much appreciate if anyone could help me out by providing some guidance to model this system.
