Free-Surface Flow Modelling with Interface Capturing Techniques

MARIN, HSVA and TUHH are jointly developing the RANS-code FRESCO. The freesurface modelling part of the code is based on interface capturing. Results with well-known discretization schemes, like CICSAM and HRIC, are presented for artificial benchmark problems and two dam-break problems. They will be compared with experimental data as well as results obtained with an alternative code, based on interface tracking. A critical evaluation is finally given, leading to the conclusion that the interface capturing scheme in FRESCO should not be governed by the Courant number
