Hello.

I am trying to simulate the flow of air inside a machine in Ansys Fluent, for my master's thesis.

The particularity is that the air is sucked in by an axial fan, and I intend to observe its flow until the machine exits.
If I assume that the air enters other than with the fan, I get good results.
But if you do the fan simulation, the results are bad.

I saw several tutorials but most of them are really simple, nothing to do with the "real life".

The machine has a main body (called case), fan (that i have substracted from the rotating body) and the rotating body.

I'm doing mesh motion with k-epsilon model in transient mode.

Any help is very appreciated.

Thank you.
