| Sažetak: | The zero-equation model (ZEM) has been generalized for aerodynamic
applications by eliminating the thickness of boundary-layer (BL) dependency to
construct the stress length parameter . The SED (Structural Ensemble
Dynamics) postulate evaluates the using the order function based on
universal multi-layer structures for wall turbulence. The SED concept is further
employed to optimize the profiles of the turbulent kinetic energy and
dissipation rate with turbulent BL flows. Results demonstrate that the multilayer ZEM receives a remarkable achievement in the prediction of wall-bounded
turbulence and thus, prevails over the drawbacks encountered in most algebraic
turbulence models. |
