SPH Modelling of Sea-ice Pack Dynamics

Abstract: The paper is concerned with the problem of sea-ice pack motion and deformation under the action of wind and water currents. Differential equations describing the dynamics of ice, with its very distinct mateFfigrial responses in converging and diverging flows, express the mass and linear momentum balances on the horizontal plane (the free surface of the ocean). These equations are solved by the fully Lagrangian method of smoothed particle hydrodynamics (SPH). Assuming that the ice behaviour can be approximated … Show more

“…This configuration was chosen for simulations, since it generates both converging and diverging ice flows in the pack domain. Detailed equations describing the wind velocities in the vortex field can be found in papers by Flato (1993), Morland and Staroszczyk (1998) and Staroszczyk (2017). Here we only note that the wind speed is zero at the vortex centre, increases linearly from zero to its maximum value u 0 at some distance R 0 from the vortex centre, and then decreases monotonically to zero with the distance increasing to infinity.…”

“…In the calculations, the kernel function W was adopted in the form of a quintic spline function proposed by Morris (1996). As in an earlier paper by Staroszczyk (2017), the standard smoothing kernels W were modified by following an approach proposed by Belytschko et al (1998). This approach makes it possible to better approximate the field variables at discrete particles located close to the open sea boundaries, so that the current positions of these moving boundaries are traced more accurately.…”

“…Following Wang et al (1998), Ji et al (2005) implemented a new viscoelastic-plastic rheology that was in better agreement with observations from the Bohai Sea. Recently, Staroszczyk (2017) proposed a sea-ice model considering ice behaving as a compressible non-linear viscous material with a (dimensionless) contact-length-dependent parameterization for floe collisions and rafting (Gray and Morland, 1994;Morland and Staroszczyk, 1998). In all of the above, except for Gutfraind and Savage (1997), the same ice particle density definition is used.…”
