Two-equation eddy viscosity model
One-equation eddy viscosity model
Algebraic eddy viscosity model
is the mixing length.
Algebraic model for the turbulent kinetic Energy:
is the shear velocity
Algebraic model for the mixing length, based on (4) :
, is the hydrodynamic roughness
the algebraic eddy viscosity model is therefore:
