Internal, compressible flow problem

Hi All,
I am trying to run a simulation in fluent of the air intake for my FSAE car. it has a 20mm restriction which makes the flow transonic and so i am trying to use a compressible air model in FLUENT. I have attached a picture of the part BCs: pressure inlet 0Pa Pressure-Outlet -36000Pa with target mass flow outlet of 0.1kg/s the outlet values have been generated from my GT power model of the engine. i have used a Hemi-spherical and a cylindrical inlet domain to represent the atmosphere above the inlet. So far any results which i get are garbage and most of the time the residuals just blow. Can anyone help? Is there something which i am doing wrong with boundary conditions or something? Thanks in advance Last edited by Tom_allchurch; February 5, 2015 at 16:18. |

Just so I understand what you are saying - you are using an incompressible model to simulate transonic flow, and you are getting garbage results. Is that a correct interpretation?

Sorry using a compressible model, I'll edit the description now
Thanks |
