The paper provides some results of a new procedure (CAD and CFD) to analyze the hydrodynamic aspects of the interactions between virtual maritime emerged breakwaters and regular waves. The structure is modeled into numerical domain, very much like the real world or the physical laboratory testing, by overlapping individual three-dimensional elements (AccropodeTM), and the computational grid is fitted so as to provide enough computational nodes within the flow paths. Therefore the filtration of the fluid within the interstices of a concrete blocks breakwater, is evaluated by integrating the Reynolds Averaged Navier-Stokes equations (RANS) inside the voids rather than making use of the “porous media” approach. For the results’ validation, the numerical run-up and reflection effects were compared with some empirical formulas and some similar laboratory tests.

Abstract
The paper provides some results of a new procedure (CAD and CFD) to analyze the hydrodynamic aspects of the interactions between virtual maritime emerged breakwaters and regular waves. The structure is modeled into numerical domain, very much like the real world or the physical laboratory testing, by overlapping individual three-dimensional elements (AccropodeTM), and the computational grid is fitted so as to provide enough computational nodes within the flow paths. Therefore the filtration of the fluid within the interstices of a concrete blocks breakwater, is evaluated by integrating the Reynolds Averaged Navier-Stokes equations (RANS) inside the voids rather than making use of the “porous media” approach. For the results’ validation, the numerical run-up and reflection effects were compared with some empirical formulas and some similar laboratory tests.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
