| dc.description.abstract |
A new zero-equation model (ZEM) is devised with an eddy-viscosity
formulation using a stress length variable which the structural ensemble
dynamics (SED) theory predicts. The ZEM is distinguished by obvious physical
parameters, quantifying the underlying flow domain with a universal multilayer structure. The SED theory is also utilized to formulate an anisotropic
Bradshaw stress-intensity factor, parameterized with an eddy-to-laminar
viscosity ratio. Bradshaw’s structure-function is employed to evaluate the
kinetic energy of turbulence k and turbulent dissipation rate 𝜺𝜺. The proposed
ZEM is intrinsically plausible, having a significant impact on the prediction of
wall-bounded turbulence. |
