Hey guys!
I want to simulate a stirred reactor.
First I want to make a model in 2d.
Which method should I use to simulate the mixer?
Make a zone of rotating fluent (like in case of MRF)?
Or just set mixer = moving wall?
Also, in case of "rotating fluent", What should be the size of the rotating zone near the mixer?

I tried to find something about it on the forum, but I could not find a clear answer (also I completed all basic Fluent turtorials).

Hey, Any tips?

Hi,
You can't do it in 2D without having the experimental velocity profile in the proximity of blades. Regarding to which rotating approach is suitable, it depends on your model, i.e. whether it's steady or having baffles. For steady state problem, you can use MRF, else you have to use sliding mesh (moving mesh). If the model doesn't have baffles, you can use SRF. Only rotate the encircled zone around the mixer and leave the other zone as stationary. It's easy and will work. Try it.
