Hi, everyone, Could you possibably tell me how to define the compressible non-newtonian fluid in Fluent?

Thanks a lot!

you can define the fluid by creating a seperate fluid properties entry in the materials menu. then import the viscosity curves as a .crv file from notepad or excel. when you select the solver make sure you envoke the turbulent compressible k-e model.

you will notice convergence oscillates but dont worry just keep waiting for the residules to converge.

peace brother! smoke em if ya got em!

hi,buzz, thank you so much for your reply. however, i am confused about the .crv file. do you mean using the UDF? please give me some details.

thanx again bob
