The K-omega model is one of the most common turbulence models. It is a two equation model, that means, it includes two extra transport equations to represent the turbulent properties of the flow. This allows a two equation model to account for history effects like convection and diffusion of turbulent energy. The first transported variable is turbulent kinetic energy, k. The second transported variable in this case is the specific dissipation, \omega. It is the variable that determines the scale of the turbulence, whereas the first variable, k, determines the energy in the turbulence.
