Evaluación de un diseño de rompeolas bajo condiciones de oleaje extremo utilizando dinámica de fluidos computacional (CFD).

Abstract

Coastal areas are affected by different conditions such as waves or erosion, to reduce these impacts coastal protection structures such as breakwaters are built. Ecuador does not have numerical computational models that show the processes that occur in the interaction of a fluid in a structure, this is why this integrative project aims to evaluate a conceptual design of a breakwater previously proposed in San Pedro - Santa Elena, by analyzing the speeds and pressures of the waves that act on the protection structure, using REEF3D to improve its efficiency and durability. Using a methodology defined in 5 phases, the tools that were used to obtain the results in the computational model are shown. A comparison of speeds and pressures was made for designs 1 (breakwater without slope toe) and 2 (breakwater with slope toe) for two extreme wave scenarios. Because design 2 has a slope footer, and its main objective was to dissipate wave energy, the pressures exerted on the fluid in the structure decreased compared to design 1.
