✦ Synopsis

Systematic tests have been performed to study the behaviour of a numerical method developed to calculate 2D, steady free surface Β―ows. The Reynolds equations are solved in the physical space by employing a nonorthogonal staggered grid, while the kΒ±e model is adopted to approximate the Reynolds stresses. The free surface is calculated following an iterative procedure and various parameters that affect convergence and accuracy of the numerical solution have been examined. Calculated results are compared with measured data for two cases, i.e. the wave generation above a bottom topography at various Froude numbers and the free surface formation above a submerged hydrofoil.

An algorithm to simulate steady, viscous free surface flows is presented in this paper. A Picard-type approach wherein the flow and free surface updates are performed alternately is utilized to iterate for a solution. The procedurr is intended for large-scale two-or three-dimensional problems. A sur
