HYDRODYNAMIC PERFORMANCES OF A WALL TYPE BREAKWATER-A PHYSICAL AND NUMERICAL APPROACH

Abstract

This paper investigates hydrodynamic performances of a wall-type breakwater through a physical model approach and validated using a numerical model based on the Volume of Fluid (VOF) method. The investigations are carried out for varying wave characteristics with the depth of water, 0.50 m. A 2D numerical wave flume is developed using ANSYS-Fluent platform by considering the VOF method and incompressible open channel fluid flow. The wave boundary conditions are adopted by solving the Reynolds-Averaged Navier Stokes equations (RANS equation) especially with the k—? model to examine the effects of turbulence on the numerical results. The hydraulic performance characteristics on the wall-type breakwater are analyzed for different wave characteristics. It is found that results obtained from the numerical investigations are in good agreement with the experimental ones. © 2021ANAME Publication. All rights reserved.
