Inlet Boundary Conditions with experimental data

MissCFD · September 19, 2016, 11:22

Hello, I would like to know how "dangerous" it is to use experimental data (velocity profil) as inlet boundary conditions ? Indeed, experimental data can have slight inconsistencies between them and so they don't respect exactly the continuity equation ...

Thank you !

A simulation requires an accurate description of the boundary conditions. If you can specify it accurately enough with experimental data then that sounds good to me. But note the CFD requires the boundary conditions to be well posed and numerically stable.
