A Kinetic Perspective on k - ϵ Turbulence Model and Corresponding Entropy Production
In this paper, we present an alternative derivation of the entropy production in turbulent flows, based on a formal analogy with the kinetic theory of rarefied gas. This analogy allows for proving that the celebrated k - ϵ model for turbulent flows is nothing more than a set of coupled BGK (Bhatnaga...
