Special Issue Information

Dear Colleagues,

In recent years, many novel computational marine hydrodynamic (CMH) methods, such as overset grid techniques, adaptive refined mesh methods, Cartesian grid methods, meshless particle methods, high-order-spectral methods and Lattice Boltzmann methods, as well as machine learning, have been developed in order to tackle the complicated and violent flows around marine structures, such as surface ships, submarines, offshore wind turbines and floating platforms, etc. All such complicated and violent flows are among the most difficult topics in marine engineering due to the large span of spatial and temporal scales involved. Some of the important topics are marine vehicle resistance and propulsion, controllability, wave loads, wave induced motions, and energy and ecology considerations, including the green water of ship motion in waves, the self-propulsion of ship motion, LNG tank sloshing, wave run-up and impact loads on floating platforms with a mooring system, VIV for risers and VIM for deep-sea platforms, wake flows of offshore floating wind turbines, slamming, the water entry/exit of bodies, and submarines in stratified flows both at the model scale and full scale, among others. The correct understanding of and application of hydrodynamics in marine vehicles and structures are vital in their design and operation. The aim of this Special Issue of Computational Marine Hydrodynamics (CMH) is to provide a platform for disseminating recent advances in novel computational marine hydrodynamic methods and exploring outstanding problems in computational marine hydrodynamics for further research and applications.

Wave concentrators have important application value in ocean engineering. Moreover, the performance of a concentrator on structural protection is important in the context of the complex ocean environment. A series of numerical simulations of the self-protected energy concentrator (SPEC) is performed under nonlinear wave conditions. The SPEC includes eight truncated cylinders arranged in a concentric circle. The performance of SPEC and the distribution of fluid field are studied by establishing a computational fluid dynamics (CFDs) model. It can be concluded that increasing wave steepness can weaken the self-protection performance and concentration effects due to its strong nonlinearity. The wave directions have little effect on the performance of SPEC. In addition, the change based on the target wave number can result in poor performance of SPEC. Full article

Wakes produced by underwater vehicles, particularly submarines, in density-stratified fluids play a pivotal role across military, academic, and engineering domains. In comparison to homogeneous fluid environments, wakes in stratified flows exhibit distinctive phenomena, including upstream blocking, pancake eddies, internal waves, and variations in hydrodynamic performance. These phenomena are crucial for optimizing the operation of underwater vehicles. This review critically assesses the hydrodynamic and thermodynamic aspects of these wakes through an integration of theoretical, experimental, and numerical approaches. The hydrodynamic wake evolution, comprising near-wake, non-equilibrium, and quasi-two-dimensional regimes, is scrutinized. The underlying physics, encompassing energy transformation, vertical motion suppression, and momentum dissipation, are analyzed in detail. Special emphasis is placed on numerical methods, encompassing diverse approaches and turbulence models and highlighting their differences in fidelity and computational cost. Numerical simulations not only provide insights into the intricate interplay among various factors but also emerge as a crucial focal point for future research directions. In the realm of thermodynamic wakes, we delve into the thermal wake induced by the discharge of high-temperature cooling water and the cold wake resulting from the stirring of seawater. The generation, evolution, and ascent to the free surface of these wakes are explored. Additionally, this review identifies and analyzes current research shortcomings in each aspect. By systematically addressing existing knowledge gaps, our study contributes novel insights that propel academic progress and bear significant implications for submarine engineering. This work not only enhances our understanding of the intricate dynamics involved but also provides a foundation for future research endeavors in this critical field. Full article
