About this document
Enhanced DDES Model for Turbulence by wgy888417 is a document available to read on EtoBox.
This document describes a new variant of the delayed detached eddy simulation (DDES) model that uses a Smagorinsky-type eddy viscosity formulation with a clipped length scale to limit the production term, rather than limiting the dissipation rate as in previous DDES formulations. The length scale is also modified to address the "log-layer mismatch" issue seen in standard DDES without additional blending functions. The model is validated for channel flow and separated flows, and its behavior is compared to t
