Simple question about pipe flow
I have a problem. There are two mass flow inlet BCs and one pressure outlet BC in my mesh. Flow temperatures at the inlets are 320K and 350K. Material is air. Maximum velocity is less than 0.25 Mach.
I would like to know that as if I have to simulate this flow compressible (due to temperature and velocity values) or not?
No, unless you have some additional energy release and want to describe sound waves propagation. All you need is conventional Boussinesq approximation.
