A new three-dimensional finite-volume non-hydrostatic shock-capturing model for free surface flow

Abstract: In this paper a new finite-volume non-hydrostatic and shock-capturing three-dimensional model for the simulation of wave-structure interaction and hydrodynamic phenomena (wave refraction, diffraction, shoaling and breaking) is proposed. The model is based on an integral formulation of the Navier-Stokes equations which are solved on a time dependent coordinate system: a coordinate transformation maps the varying coordinates in the physical domain to a uniform transformed space. The equations of motion are discr… Show more

“…In this paper we adopt the new approach proposed by Gallerano et al [14] in which the motion equations are expressed in terms of variables that are Cartesian based: only the vertical coordinate is expressed as a function of a time-dependent curvilinear coordinate that follows the free surface movements.…”

“…The shock-capturing scheme [14] does not need to use any "a priori" criterion to identify the location of the initial wave breaking point, and it is able to correctly assign the boundary conditions on the free surface. In this model, by using a computational domain that has a limited number of points along the vertical direction, the numerical wave height fits the experimental measurements before the breaking point and the wave breaking is tracked correctly.…”

“…A recent evolution of the three-dimensional models that adopt a time-varying coordinate makes use of shock-capturing numerical schemes that are able to explicitly simulate wave breaking. In Bradford (2011), Ma et al (2012), Cannata et al (2017), and Gallerano et al (2017), the Navier-Stokes equations are written in a coordinate system in which the horizontal coordinates coincide with the Cartesian coordinates and the vertical one is a time-dependent curvilinear coordinate. These models are able to simulate in fully three-dimensional form the wave propagation from deep water, where dispersive effects are dominant, to surf and swash zones, where the nonlinearity of the motion equations allows to represent the shoaling and the wave breaking, and do not require to switch off any term of the equations.…”
