need help! for vane rotary compressor cfd
hello..i want to simulate suction process for rotary vane compressor..it is possible to use ansys fluent..and can you guide me in doing that..im a student..this is for my master project..t.q

Yes it is. You can simulate the flow involved rotor & stator interaction with Multiple Reference Frame approach (MRF).
|
For advise on my part, I think you need to change your project because it is tough ask for masters scope because
1. there is a translational motion of vanes in and out of vane cavity, to incorporate it you need to write a Udf 2. For Rotational motion of the rotor, you need to write another Udf 3. you need to adjust them in such a way that during rotational motion the vanes translational motion follow the cavities 4. I haven't found any good reference related to this work in literature, i always believe one should first do the literature review and make sure that he has enough references and data. |
CFX has better options for this. See this

Axial compressor is different from rotary vane compressor, it can be done with simple sliding mesh technique. you can check rotary vane compressor working on internet and you will agree with what CFD seeker has posted. You can model it using immersed solid approach posted by far, but i am unsure about its experimental validation because it can not account for in and out motion of vanes in the cavity.

thanks for the link..if i want to simulate the suction port and discharge port of the compressor how im going to validate this?
|
What about flownex? Can it be done using flownex?
