Abstract
In the previous paper, I proposed a one-equation-type subgrid-scale (SGS) model for a Large Eddy Simulation (LES) of plant canopy flows. In that paper, the SGS turbulent energy equation was derived from the equations of continuity and Navier-Stokes. The SGS turbulent energy equation was closed by modeling several unknown terms which appeared in the equation. In this paper I tried to modify the modeling of the turbulent diffusion terms and the viscous dissipation rate. The turbulent diffusion terms were modeled in a unified way. The viscous dissipation rate was modeled using two length scales.
