An analytical model for oblique wave interaction with a partially reflective harbor structure

Interaction of Swell and Sea Waves with Partially Reflective Structures for Possible Engineering Applications

“…Also, the phase lag shows a similar variability, with 0.2π < Φ < 0.5π for sensor S5 and 1.5π < Φ < 1.7π for sensor S7. We notice the presence of quasi-antinodes and surface elevations in phase opposition (Φ ≈ π) which is critical for the study of the loads acting on the plate [8]. These results are in agreement with the results in Jalon et al, (2019) [8], where the same structural configuration is studied analytically.…”

These results are in agreement with the results in Jalon et al, (2019) [8], where the same structural configuration is studied analytically. The maximum values of the capture coefficient (a proxy for the transmission coefficient), with the presence of quasi-antinodes, are obtained for B/L ≈ 0.6 (R1a-b-c-experiments).…”

“…Jalon et al, (2018) [8] presented an analytical model to optimize the design configuration of a vertical thin barrier concerning different criteria, such as harbor tranquility or wave energy extraction using a prototype setup as the once presented in this work. Their results showed the presence of nodal and antinodal frequencies of the spectra on both the leeward and seaward side depending on the geometrical configuration and the incident wave characteristics focusing on the relative submergence (d/h) and relative width (B/L) parameters.…”

“…The results showed the effect of the various configurations on transmission, reflection, and energy dissipation, highlighting that the main governing design parameter could change depending on forcing conditions (for short waves the main parameter was the submergence of the barrier, for long waves it was the width of the chamber). Jalon et al, (2018) [8] presented an analytical model to optimize the design configuration of a vertical thin barrier concerning different criteria, such as harbor tranquility or wave energy extraction. Other types of structures, e.g., slotted-, porous-, and Jarlan-type barriers, have also been widely studied [9,10].…”

“…The structure consists of a thin vertical semi-submerged barrier delimiting a chamber along with an impermeable back wall. This type of structures can be used in maritime engineering applications such as harbor tranquility and energy extraction [7,8,12].…”
