Advances in Aerodynamic–Hydrodynamic Effects and Fluid–Structure Interaction Mechanisms for Offshore Wind Turbines

Dear Colleagues,

Offshore wind energy stands as a cornerstone of the global transition to sustainable power, yet the pursuit of deeper waters and larger turbines intensifies the multiphysics challenges at the fluid–structure interface. Aerodynamic loads from turbulent wind fields, hydrodynamic excitations from extreme waves, and their dynamic coupling with floating platforms and flexible blades collectively govern the efficiency, stability, and longevity of offshore wind systems. Despite recent advances, critical gaps persist in understanding the nonlinear interactions between unsteady flow physics and structural responses, particularly under typhoons and multi-directional sea states.

This Special Issue seeks to bridge these gaps by synthesizing cutting-edge research across ​​numerical modeling, ​​experimental validation​​, and ​​data-driven innovations​​ into a cohesive framework. Contributions may explore high-fidelity simulations of coupled aerodynamic–hydrodynamic structural systems, experimental techniques for synchronously capturing wind–wave–platform interactions in basin tests, and hybrid approaches that integrate machine learning with physics-based models to refine turbulence closure schemes or predict fatigue hotspots. A special emphasis is placed on methodologies that unify multiscale flow physics—from blade tip vortices to platform surge–pitch dynamics—and translate these insights into design guidelines for next-generation floating turbines. By fostering cross-disciplinary dialog among fluid mechanists, marine engineers, and renewable energy specialists, this issue aims to catalyze breakthroughs in the predictive accuracy, operational resilience, and cost-effective deployment of offshore wind technologies.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the Special Issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-anonymized peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Journal of Marine Science and Engineering is an international peer-reviewed open access semimonthly journal published by MDPI.
