Numerical wave interaction with tetrapods breakwater
Dentale, Fabio,Donnarumma, Giovanna,Carratelli, Eugenio Pugliese The Society of Naval Architects of Korea 2014 International Journal of Naval Architecture and Oc Vol.6 No.4
The paper provides some results of a new procedure to analyze the hydrodynamic aspects of the interactions between maritime emerged breakwaters and waves by integrating CAD and CFD. The structure is modeled in the numerical domain by overlapping individual three-dimensional elements (Tetrapods), very much like the real world or physical laboratory testing. Flow of the fluid within the interstices among concrete blocks is evaluated by integrating the 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 formulae and some similar laboratory tests. Here are presented the results of a first simple validation procedure. The validation shows that, at present, this innovative approach can be used in the breakwater design phase for comparison between several design solutions with a significant minor cost.

A CFD approach to rubble mound breakwater design
Fabio Dentale,Ferdinando Reale,Angela Di Leo,Eugenio Pugliese Carratelli 대한조선학회 2018 International Journal of Naval Architecture and Oc Vol.10 No.5
The paper provides some developments of a numerical approach (“Numerical Calculation of Flow Within Armour Units”, FWAU) to the design of rubble mound breakwaters. The hydrodynamics of wave induced flow within the interstices of concrete blocks is simulated by making use of advanced, but well tested, CFD techniques to integrate RANS equations. While computationally very heavy, FWAU is gaining ground, due to its obvious advantages over the “porous media”, i.e. the possibility of accounting for the highly non stationary effects, the reduced need of ad hoc calibration of filtration parameters and also e in perspective e the evaluation of hydrodynamic forces on single blocks. FWAU however is a complex technique, and in order to turn it into a practical design tool, a number of difficulties have to be overcome. The paper presents recent results about this validation, as well as insight into fluid dynamical aspects.
