Absolute Velocity Formulation

Peter Müller · September 22, 2020, 08:06

Dear all

I am trying to understand how it is possible to obtain what is known the "Absolute Velocity Formulation". I am especially interested in the conservation equation for energy and found the following document from FLUENT.

https://www.afs.enea.it/project/nept.../th/node30.htm

I tried a lot and did quite some research on google but I am not able to write down
how the "Relative Velocity Formulation" can be recast into the "Absolute Velocity Formulation" although they should be equal.

Is there anybody who could help me out on this one?

Thanks in advance

Never tried myself, but interested as well... especially how then the equations are feeded to a convective scheme like, say, the Roe one
