초록

The paper provides some results of a new procedure to analyze the hydrodynamic aspects of the interactionsbetween maritime emerged breakwaters and waves by integrating CAD and CFD. The structure is modeled inthe numerical domain by overlapping individual three-dimensional elements (Tetrapods), very much like the real worldor physical laboratory testing. Flow of the fluid within the interstices among concrete blocks is evaluated by integratingthe RANS equations. The aim is to investigate the reliability of this approach as a design tool. Therefore, for the results'validation, the numerical run-up and reflection effects on virtual breakwater were compared with some empirical formulaeand some similar laboratory tests. Here are presented the results of a first simple validation procedure. Thevalidation shows that, at present, this innovative approach can be used in the breakwater design phase for comparisonbetween several design solutions with a significant minor cost.
