I am trying to analyze air compressor in fluent
I have a geometry created in solidworks for air compressor with inlet casing fins and outlet and inside compressor blades. I am trying to do cfd analysis using fluent. What boundary conditions should i try? I tries pressure inlet and pressure outlet but the model diverges even tries mass flow inlet and pressure outlet then x-momentum diverges. Which model I should use i used LES solver and Spalart-Almaras solver. but got divergence in both models Can anybody help me out with this? Thanks |

Firstly, try Fluent subforum and some images of your problem (Mesh, BCs etc.) would help the readers to comment precisely..

It sounds like you have a problem with your setup (either a mesh or a boundary condition problem). Or it may be a less serious problem, like a bad initial guess.
A pressure inlet & pressure outlet is the most robust boundary condition pair. If you cannot get your simulation to work with those, then you have a moderate/serious problem. Make sure your mesh is reasonable quality. Make sure your boundary conditions are correct. Make sure your initial conditions are reasonable. Try a simulation with constant material properties before jumping into doing full non-linear properties. |

Thanks for your reply.
Below I have inserted images which are self explanatory I am stuck with models not behaving as they should. I did all manual calculations for air compressor. Its outlet temp. should be upto 200 Deg.Celcius. But in analysis it is something vague value. I tried K-epsilon model with pressure based solver in fluent. the pressure ratio is 3.5 bar. Kindly suggest something so that I can carryout its analysis. Thanks Last edited by kedarjan; March 10, 2016 at 10:01. |
