Resumen:
The free surface incompressible fluid flow is solved through an
arbitrary Lagrangian-Eulerian strategy, considering a deformable
single-phase domain with an artificial boundary, which is managed
through an absorbing technique for avoiding spurious wave reflections at
the contour. This absorbing strategy is based on the shallow water
approximation, as introduced in previous works (Absorbing Boundary
Conditions for Free-Surface Flows in Open Domains, Storti, M.,
Battaglia, L., Paz, R., and DElía, J., 10th World Congress on
Computational Mechanics - WCCM 2012; Interface-Tracking Free-Surface
Flows in Open Domains, Battaglia, L., Storti, M. and DElía, J.,
Mecánica Computacional Vol. XXX, pp. 2209-2223). The resolution scheme
consists of three numerical stages: (i) the fluid flow stage, where the
incompressible Navier-Stokes equations for viscous fluid flows are
solved; (ii) the free surface transport; and (iii) the mesh movement,
solved as a pseudo-elastic problem. The strategy is used for solving
some three-dimensional free-surface flows in domains with at least one
artificial boundary, emphasizing the effect of the proposed absorbing
layer.
