COMPUTATION OF INTERNAL FLOW WITH FREE SURFACES USING ARTIFICIAL COMPRESSIBILITY

In this article an upwind flux-differencing scheme using artificial compressibility is generalized to allow time-accurate computation of incompressible flows on a dynamic grid system. By treating the free surface as a moving grid line that connects in a Lagrangian fashion, the scheme can be applied to solve a variety of free surface flows of moderate surface deformation. The surface tension effects can also be included using a source term and via boundary condition.
