How to evaluate the torque on a rotating part (Impeller or mixer)?

Hi everybody,
Does anyone know whether it is possible to evaluate the force acting on a rotating body that interacts with both fluid and solid particles and the corresponding torques?

Thank you for your help.

I’m not sure I understand the question. What’s driving the rotation? In a case like the 3D mixer tutorial, you are controlling the speed of the mixer, so you can compute the (constant) torque directly - but I think you may be looking for something else … are you looking for the torque contributions from particle collisions?
