what is the 'Wall Turbulent Prandtl Number'?
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?

prandtl number
how to find wall prandtl number and energy prandtl number ?
i'm trying to resolve case about turbulent flow in this paper c miu , c1epsilon, c2epsilon, sigma k, sigma epsilon are known with c = 0.25, but i don't know what is c and what is c for
