Absorbing Boundary Conditions for Free-Surface Flows in Open Domains

Mario Alberto Storti


The presented scheme is a first order AL for the NS equations with free surface. Good absorption is observed with absorbing layer of 1 wavelength or less. Extension to higher order AL's or ABC's is an ongoing work. The AL has been shown for a tracking surface ALE formulation, but can be extended to Level-Set or VOF schemes as well.
