A Potential Flow Solver for Nonlinear Free Surface Problems Based on the Finite Volume Method

Abstract A potential flow solver based on the Finite Volume method (FVM) solves free surface problems. The solution procedure incorporates the implicit time integration scheme both for the bulk flow and for the free-surface boundary. Special care has been taken for the determination of cell fluxes, so that the computations can be carried out properly also in curvilinear coordinate systems. The method is validated with a transom-stern model (ILE model) using three different Froude numbers. The wave heights correspond reasonable well to the results obtained using other potential flow solvers.
