sezo85 is on a distinguished road
Hi all,

I am working on a quasi-1D Euler solver for axial compressor and i am in the process of modelling bleeds.
I was wondering which source terms I should include in my set of equations and how to calculate them.
I am calculating the flow extracted using a simple orifice flow analogy but how should I calculate the change in energy (enthalpy)? Do I need to calculate changes in momentum as well?
Any help would be really appreciate.
Thank you very much.
