Actually, the issue we're talking about is the transport equation of the turbulent kinetic energy dissipation rate rather than the TKE equation. So, instead of Eq. [122], you should refer to Eq. [123-124] in the article by Enwald et al. (the same as Eq. (151) in the article by Peirano and Leckner).

The source of dissipation in Fluent theory guide is defined as:

Note that the whole term at the right-hand side of the equation* i* represents the source term.

In the article, it is defined as

Please read carefully the figures in the last reply, and you can find the details of the derivation and comparison.
