Abstract

This article deals with an original numerical method for computation of two-dimensional laminar free surface flows in viscous and incompressible fluid. With this method exact non linear free surface boundary conditions are taken into account. Equations are discretised by finite differences and a modified Rhie and Chow method is used to write the discrete pressure equation. The coupled linear system in velocities, pressure and free surface elevation unknowns is solved by CGSTAB algorithm.

Two-dimensional results are presented for waves propagation in shallow water and flows around free-surface piercing bodies in forced motion.
