Abstract:

In the field of experimental tests in 2D wave tanks, it is of vital importance to know the reflection generated by the structures responsible for dissipating the waves that reach the end of the installation. The field of application of this type of tanks is wide and is generally directly related to technology, structures, and, in general, systems that perform their functions in the sea environment. During the process of validating the behavior of these systems, scale models of the prototypes are usually tested in wave tanks, minimizing the influence of the waves reflected in the physical limits of the tank itself. In this regard, the present work has characterized the phenomenon of dissipation and reflection of the incident wave on a mobile solid structure placed at one end of a 2D wave tank, defining the dependence of the dissipation and reflection phenomenon for each typology. wave (heights and periods) and the geometric arrangement of the solid surface. The experimental work contains a total of 256 individual tests, where the interaction of 8 monochromatic waves with different height, period, wavelength and depth has been characterized. These waves have interacted with 10 beach positions with different inclination angles (between 8 and 26º). For all the cases, the reflection coefficient has been extracted from the envelope curve resulting from the superposition of the incident wave and the reflected wave in the structure. The result of the study provides optimal inclination positions of the parabolic absorption system that minimize the reflection coefficient. The results are expressed as a function of the properties of the incident waves and on the corresponding Iribarren dimensionless number.
