Introduction to Turbulence Modeling TURBULENT FLOW
Shortcomings of One-Equation Models
Use of an algebraic equation for the length scale is too restrictive.
Transport of the length scale is not accounted for. Transport of Second Scale (Boundary Layer)
The transport of a second turbulence scale, z, is given as
z-Equation:
where
= diffusion
= production
= destruction,
= secondary source
