Parametric Design and Numerical Investigation of Hydrodynamic Characteristics of a New Type of Armour Block TB-CUBE Based on SPH Method

Abstract

Based on the open-source code DualSPHysics, a numerical model was conducted to simulate the regular wave transformation on the slope breakwater with artificial block, and the simulation results were verified according to the measured data from the physical experiment. The deviation between the numerical model and the measured data was less than 6% and 9% in wave run-up and overtopping, respectively, which demonstrated the model can reliably capture the wave evolution on the breakwater with an artificial block. Based on this verified model, the size of the artificial block was adjusted to obtain optimal wave-damping effects. Once obtained, the hydrodynamic characteristics of the optimized new artificial block TB-CUBE were further studied, and the effects of the breakwater slope, water depth in front of the breakwater, incident wave period, and the height on wave run-up were all analyzed. Finally, an empirical formula for wave run-up on this type of article block was suggested through data-fitting, for which the correlation coefficient is 0.981.

“…In this book, five papers present the development and/or validation of various RANS models. Peng et al [13] presented the simulation of a regular wave transformation on the slope of breakwater with an artificial block using DualSphysics. Brito et al [14], applying the same model, employed DualSphysics to study the power absorption of a constrained wave energy hyperbaric converter (WEHC) under full-scale sea wave conditions.…”

Hydraulic Response and Overtopping Performance of Single-Layer Double Cube Unit Armored Mound Breakwater

“…In recent decades, there has been a resurgence of interest in structurally robust forms: Accropode ® I, Coreloc ® , Xbloc ® (CIRIA [1]), and Crablock (Salauddin et al [2,3]), and particularly for simpler shapes, Cubipod ® (Gómez-Martín and Medina [4,5]) and C-ROC (Perrin et al [6]). It is also worth mentioning that during recent years, many new regular-placed armor blocks have been introduced in the literature, such as Xbloc ® Plus (Reedijk et al [7]), Chi (Park et al [8]), Starblock (Safari et al [9][10][11][12]), and TB-CUBE (Peng et al [13]).…”
