High-fidelity numerical simulation of solitary wave propagation

Abstract As a classic problem in oceanographic and coastal engineering hydrodynamics, solitary wave propagation is used to benchmark novel high-fidelity numerical model based on the Navier–Stokes equations. The combines Finite Volume method Merged Stencil with 3rd-order reconstruction (FVMS3) Tangent of Hyperbola for INterface Capturing Quadratic surface representation Gaussian Quadrature (THINC/QQ) schemes. Accurate predictions are made inviscid viscous waves propagating plane sloping beaches. Model performance assessed by comparing analytical solutions, alternative results obtained using interFoam solver OpenFOAM commercial flow software ANSYS Fluent, as well experimental data. It demonstrated that present significantly reduces undesirable effects, including energy loss, decay, phase shift, overestimation velocity profile even after long duration computations, suppressing dissipation dispersion.
