Finite element approximation of 3D non-hydrostatic turbulent coastal ocean flows using a LES model
In this paper we present a stabilized finite element method for three-dimensional,
non-hydrostatic, turbulent coastal ocean flows. The model we have developed, named
HELIKE, incorporates also surface wind stress, bottom friction, Coriolis forces and
several closure models for both the horizontal and the vertical turbulent eddy vis-
cosity coefficients. Unstructured meshes are employed so that complex geometries
can be accurately approximated, and implicit time stepping allows to use large time
steps. Numerical results are presented in various test cases, in which comparisons
between different turbulence models are provided
