Special Issue Information

Dear Colleagues,

Marine computational fluid dynamics (CFD) is a pivotal tool in the design and analysis of ships, underwater vehicles, offshore structures, and marine energy devices. It enables the prediction of hydrodynamic performance, the assessment of energy efficiency, and the mitigation of environmental impacts. With the marine industry striving for sustainability and innovation, the role of CFD in understanding and harnessing the power of the oceans has never been more critical. This Special Issue invites researchers, engineers, and scholars to contribute original research articles, review papers, and case studies that push the boundaries of marine CFD. Topics of interest include, but are not limited to, the following:

  • Advanced simulation techniques for turbulent flows, wave dynamics, fluid–structure interactions, and ship hydrodynamics;
  • CFD applications in the conceptualization, design, and optimization of hull shapes, propellers, marine renewable energy devices, and other marine structures;
  • Environmental impact assessments using CFD include wave and wind impacts on marine infrastructure, oil spill modeling, marine ecosystem protection, and underwater noise pollution;
  • Integration of CFD with other emerging technologies, such as artificial intelligence, data assimilation, machine learning, and digital twins, will revolutionize marine engineering solutions;
  • Case studies on the successful applications of CFD in maritime industry projects.

Through this Special Issue, we aim to foster collaboration, inspire innovation, and contribute to the sustainable development of the marine industry.

Hydrokinetic tidal energy is one of the few marine renewable energy resources with sufficiently mature technology for commercial exploitation. However, several parameters affect its exploitability, such as the minimum speed threshold, ambient turbulence levels, or tidal asymmetry, to name but a few. These parameters are particularly important in regions with lower mean speeds than those in first-generation sites, such as the North Sea. The Gulf of California is one of those regions. In this paper, a Delft3D Flexible Mesh Suite (Delft3D FM) model in barotropic configuration is set up over the Gulf of California using a flexible mesh with resolution varying from O (500 m) in the deep regions to O (10 m) in the coastal regions. A simulation is run over the year of 2020, with a tidal forcing of 75 components. The model is validated at four tidal gauge locations and four Acoustic Doppler Current profiler (ADCP) locations. The speed, U, and tidal power density (TPD) indicators used for the validation were the annual means, the annual means for speeds above the 0.5 m s−1 threshold, the annual means of the spring tide maxima, and the annual maxima. The contour maps of the annual means, that is, the annual means for speeds above the 0.5 m s−1 threshold, allow us to identify tidal energy hot spots throughout the Gulf of California, particularly in the Great Island region (GIR). In this region, these hot spots have higher U and TPD values, in agreement with previous studies. The patterns of circulation around Tiburón Island and San Esteban Island on the East, and Ángel de la Guarda Island and San Lorenzo Island on the West, the four islands in the region with the highest tidal energy potential, are also discussed while recognizing that Tiburón Channel, between Tiburón Island and San Esteban Island, has proved to be the best siting location, based on the technical results obtained so far. The hot spots sites are further characterized by computing the tidal asymmetry in these small regions, showing the locations of the sites with smallest asymmetry, which would be the best for tidal energy exploitation. The hot spots around San Esteban Island are particularly important because they have the largest TPD in the GIR, with the model predicting a TPD on the order of 500–1000 W m−2. Here, complementary field measurements obtained with two ADCPs, close to San Esteban Island, one at 15 m depth, SEs (shallow region), and the other at 60 m depth, SEd (deep region), produced TPDs of 1200 W m−2 and 400 W m−2, respectively. The analysis of the vertical profiles and the tidal asymmetry over the vertical shows the importance of developing 3D models in future investigations. Full article

Focusing water surface waves is a promising approach for enhancing wave power in clean energy harvesting. This study presents a novel method that simplifies the wave-scattering problems of large-scale three-dimensional (3D) focusing blocks by decomposing them into scattering problems of two-dimensional (2D) phase regulators. The phase lags of transmitted waves over such 2D structures of various heights and thicknesses are investigated using both linear potential flow theory and numerical simulations based on smoothed-particle hydrodynamics (SPH). Due to propagation path differences of a converging wave, our approach compensates for circular phase differences within a maximal collection angle by optimizing the geometries of 2D phase regulators. Based on this concept, we designed three types of submerged structures and tested them in a 3D numerical water tank. All three structures successfully converted monochromatic plane waves into circular waves, which then converged at the designated focal point. This study offers a potential method to enhance the collection efficiency of monochromatic and regular waves for wave energy converters. Full article
