In
computational fluid dynamics, the k–omega (k–ω) turbulence model is a common two-equation
turbulence model, that is used as an approximation for the
Reynolds-averaged Navier–Stokes equations (RANS equations). The model attempts to predict
turbulence by two
partial differential equations for two variables, k and ω, with the first variable being the
turbulence kinetic energy (k) while the second (ω) is the specific rate of
dissipation (of the turbulence kinetic energy k into internal thermal energy).
The eddy viscosity νT, as needed in the RANS equations, is given by: νT = k/ω, while the evolution of k and ω is modelled as:
For recommendations for the values of the different parameters, see Wilcox (2008).
