A study of the impact of plunging waves on the inverted L-shaped breakwater structure based on SPH method
An obvious slamming phenomenon appears at the inverted �L-shaped� breakwater when impinged by waves. Based on the DualSPHysics numerical program, a numerical tank which can simulate plunging waves is established. The single-phase flow model is adopted in this program, GPU parallel acceleration p...
