Summary
This Special Issue focuses on cutting-edge research in aerodynamic flows, with particular emphasis on fluid–structure interactions (FSI) and the use of high-fidelity simulations to optimize aerodynamic performance and structural design. We invite contributions that advance the understanding of unsteady, transitional, and turbulent flow behavior around complex geometries, highlighting the coupling between fluid dynamics and structural response. Topics of interest include boundary-layer development, flow separation, vortex dynamics, aeroelastic phenomena, and aeroacoustics, explored through analytical, numerical, and experimental approaches.
Submissions leveraging advanced computational fluid dynamics (CFD), including direct numerical simulation (DNS), Reynolds-Averaged Navier-Stokes (RANS), large-eddy simulation (LES), and hybrid turbulence modeling, are encouraged, especially when used to inform the design and optimization of aerodynamic shapes and the selection of materials for structural components under aerodynamic loading. High-resolution experimental studies, such as wind tunnel testing, flow visualization, particle image velocimetry (PIV), and other state-of-the-art techniques, are also welcome, particularly when coupled with computational analysis.
We also encourage research integrating data-driven and machine learning approaches for shape optimization, surrogate modeling, active flow control, or predictive modeling of coupled fluid–structure systems. By emphasizing the interplay between fluid dynamics, structural behavior, and performance-driven design, this Special Issue aims to provide a platform for advancing predictive, robust, and efficient aerodynamic solutions applicable to aerospace, renewable energy, automotive, and other engineering systems.
Scope Topics:
· Aerodynamic Design and Optimization (e.g., airfoil/wing design, aerodynamic performance of wind turbines, vehicle and aircraft shape optimization)
· Turbulence and Flow Control (e.g., active/passive flow control, turbulence modeling, drag reduction and lift enhancement)
· Multiphysics and Multiscale Flows (e.g., aero-thermal-structural coupling, cross-scale simulations, multiphase and combustion-related aerodynamics)
· Computational and Experimental Aerodynamics (e.g., high-fidelity CFD, wind tunnel testing, data-driven and AI applications in aerodynamics)
