Abstract

Transient breaking waves exceeding a critical steepness are investigated by means of numerical simulations based on the Reynolds-averaged Navier-Stokes equations. For the approximation of Reynolds stresses four different closure models are used: the first order standard k-ε-model, RNG k-ε-model and SST k-ω-model and a second order Reynolds stress model. Up to the breaking point the influence of turbulence models is insignificant and the numerical results agree very well with laboratory PIV measurements. The turbulence quantities like turbulent kinetic energy and turbulent viscosity that develop during the breaking and post breaking process are investigated and the influence of the different turbulence models is analyzed. © 2007 World Scientific Publishing Co.
