Abstract: Using a sigma co-ordinate system a three-dimensional mathematical model for free surface flow based on the Reynolds-averaged Navier-Stokes equations is developed. The time-splitting method is used to separate advection and diffusion terms from the pressure terms in the governing equations. The hydrodynamic pressure equation is solved by a multigrid method, while the hydrostatic pressure equations are solved very efficiently by an Alternating Direction Implicit (ADI) scheme. The model is tested against available analytical solutions and experimental data. Good agreement has been achieved.
