Special Issue Information

Dear Colleagues,

Experimental and computational ship hydrodynamics have developed rapidly over the last ten years. Experimental studies extended their measurements from integral to local flow variables and from captive/semi-captive to free-running self-propelled ships, providing data at different levels for the validation of computational solvers.  Additionally, computational tools moved from inviscid flow and system-based solvers to complete physics-based methods, based on the Navier–Stokes equations. Investigations on nontraditional computational techniques, such as the LBM (Lattice Boltzmann Method), have also recently been initiated. Open source codes have accelerated these developments, and a fully simulation-based design seems more feasible than ever. The advancements of HPC (High-Performance Computing) have enabled computational tools to investigate hydrophysics at multiscales by utilizing thousands of cores. Studies have been conducted on a wide range of topics, including bubbly wake flow, propulsion and cavitation, fluid–body dynamic interaction, hydroelasticity, intact and damaged stability, deterministic and scholastic optimization, extreme events, uncertainty quantification, and verification and validation. The aim of this Special Issue is to collect some of the state-of-the-art contributions to experimental and computational ship hydrodynamics.

For safe ship berthing, all steps involved, from bringing the ship to the fairway area to directing it to the final wharf position at a desirable speed, need to be performed properly. In this article, a support system is proposed to automatically bring the ship into the berth after completing the maneuvering process. This proposed system requires no involvement of a shipmaster, enabling automatic ship berthing in marine practice. Three fuzzy controllers are proposed to conduct different tasks of berthing. The first controller is designed to control the movement of the ship in a longitudinal direction towards the wharf while the second controller stabilizes the relative bearing error with respect to the tugboat. The final controller is responsible for bringing the ship into a wharf according to crabbing motion with bow thruster and tugboat simultaneously. Compared to other approaches, ours has a wider range of adoption, better generalization capability, and is more suitable for marine practice. Comprehensive experiments in numerical simulations are carried out, showing the superior performance of the proposed support system for automatic ship berthing. Full article

A hybrid method—coupled with the boundary element method (BEM) for wave-making resistance, the empirical method (EM) for viscous resistance, and the boundary layer theory (BLT) for capture of an area’s physical parameters—was proposed to predict waterjet propulsion performance. The waterjet propulsion iteration process was established from the force-balanced waterjet–hull system by applying the hybrid approach. Numerical validation of the present method was carried out using the 1/8.556 scale waterjet-propelled ITTC (International Towing Tank Conference) Athena ship model. Resistance, attitudes, wave cut profiles, waterjet thrust, and thrust deduction showed similar tendencies to the experimental curves and were in good agreement with the data. The application of the present hybrid method to the side-hull configuration research of a trimaran indicates that the side-hull arranged at the rear of the main hull contributed to energy-saving and high-efficiency propulsion. In addition, at high Froude numbers, the “fore-body trimaran” showed a local advantage in resistance and thrust deduction. Full article
