A detailed numerical investigation of the calm-water hydrodynamic performance of an azimuth stern drive (ASD) tugboat is presented. Unsteady Reynolds-Averaged Navier–Stokes (URANS) simulations are performed to predict the total resistance, trim, and sinkage over a wide range of Froude numbers at model scale. The free-s…

In marine environments, the main cause of degradation of reinforced concrete structures is corrosion induced by the penetration of chloride ions. Durability design approaches have gradually evolved toward performance-based approaches, which are capable of more accurately assessing the behavior of structures over time a…
