When solving the energy eq'n with turbulent model, in the viscous panel, we can input turbulent prandtl number(default : 0.85).

And we can find the 'Wall Turbulent Prandtl Number(defaut : 0.85)' under the viscous panel.

Bt its usage cannot be found in Fluent Manual.

What is it?

how to find wall prandtl number and energy prandtl number ?
i'm trying to resolve case about turbulent flow
in this paper c miu , c1-epsilon, c2-epsilon, sigma k, sigma epsilon are known
with c = 0.25, but i don't know what is c and what is c for
