I`m running axial multi-stage compressor performance curve simulation and seems like I need to use Sutherland law to get closer results to experimental data in stall and surge regions.
Since I have no experience in changing the Material Data for Ideal Gas I`m afraid to make some mistakes. So I would be glad if someone has enough experience to share it with me. I`ve checked ANSYS Help and have found next values for Sutherland Law: Ref. Temperature 273 K Ref. Viscosity 1.716e-05 kg/ms Sutherlands Constant 110.4 K Temperature Exponent 1.5 Can anyone confirm these values? Thanks |
