Dear all

What is the blower fan accuracy different when use sliding mesh and multi rotating frame(MRF)? Someone could tell me about this information,or give me some suggest?

Thanks..

Best Regard !!

The problem with MRS is, that you never know in advance, how big the error will be for a special type of fan/pump/compressor.

I have seen differences of more than 100 percent !!

Thanks your response!

But I still want to simulate this blower fan..

Is there another way ? ..redo mesh ?

Or someone could have better way?

Thanks!!

Best regard!!

The best way is to run mrf at first and use the data as initial field for sliding mesh. this way you will see if there are big differences.

mrf is not too bad for most axial and radial fans.
