Study Data from Islamic Azad University Provide New Insights into Naval Architecture and Ocean Engineering (Simulating three dimensional wave run-up over breakwaters covered by antifer units)

By a News Reporter-Staff News Editor at Journal of Engineering -- Fresh data on Naval Architecture and Ocean Engineering are presented in a new report. According to news reporting out of Tehran, Iran, by VerticalNews editors, research stated, "The paper presents the numerical analysis of wave run-up over rubble-mound breakwaters covered by antifer units using a technique integrating Computer-Aided Design (CAD) and Computational Fluid Dynamics (CFD) software. Direct application of Navier-Stokes equations within armour blocks, is used to provide a more reliable approach to simulate wave run-up over breakwaters."

Our news journalists obtained a quote from the research from Islamic Azad University, "A well-tested Reynolds-averaged Navier-Stokes (RANS) Volume of Fluid (VOF) code (Flow-3D) was adopted for CFD computations. The computed results were compared with experimental data to check the validity of the model. Numerical results showed that the direct three dimensional (3D) simulation method can deliver accurate results for wave run-up over rubble mound breakwaters. The results showed that the placement pattern of antifer units had a great impact on values of wave run-up so that by changing the placement pattern from regular to double pyramid can reduce the wave run-up by approximately 30%."

According to the news editors, the research concluded: "Analysis was done to investigate the influences of surface roughness, energy dissipation in the pores of the armour layer and reduced wave run-up due to inflow into the armour and stone layer."
