A Composite Finite Element-Finite Difference Model Applied to Turbulence Modelling [PDF]

, 2007
Turbulence has been modeled by a two equation k-?turbulence model to investigate the wind induced circulation patterns in coastal waters. Predictions of the model have been compared by the predictions of two equation k-?turbulence model. Kinetic energy of turbulence is k, dissipation rate of turbulence is ?, and frequency of turbulence is ?.
