Improvements of depth-averaged κ-ε turbulence model
Abstract
The modification of depth-averaged k-ε turbulence model by introduction of “correction factors” was attempted. It was assumed that each physical quantity has a semi-empirical vertical profile of a fully-developed turbulent flow in an open-channel. Formulae for several correction factors,that express the effects of correlations of physical quantities in each term, were obtained by substitution of those profiles into 3-dimensional full k- and ε- equations. Simultaneously two modified formulae for model constants of bottom shear production terms of k and ε were also obtained.
