Default Vertical eddy viscosity in channal flow?
Posts: n/a
I am code a shallow water flow in sigma-coordinate. Now I want calculate my vertical eddy viscosity with a algebraic close modle becase the horisonal eddy viscosity is decided with a k-e modle. I only know the Coleman' formula, which is k(u*)h(z/h)(1-z/h). who can tell me some others. Thanks.
