| description abstract | This study presents a modified eddy viscosity model for describing vertical distribution of turbulent eddy viscosity in one‐dimensional fully developed asymmetric channel flows, which cannot be obtained by the traditional eddy viscosity model. A two‐power law expression, used to describe vertical distribution of flow velocity, is shown to account quite well for the major characteristics of flow in channels of asymmetric roughness. The modified eddy viscosity model, utilizing the two‐power law expression, enables formulation of a continuous distribution of eddy viscosity with positive magnitudes of turbulent eddy viscosity for asymmetric channel flows. Examples are given showing that the distribution of eddy viscosity obtained by using the modified eddy viscosity model is comparable with that obtained using Launder and Spalding's | |
