Special Issue Information

Dear Colleagues,

Computational fluid dynamics (CFD) is an approach to solving fluid mechanics problems using computer simulations that has come to be widely used in engineering applications across a range of fields such as aeronautic, civil, environmental, hydraulic, chemical, and mechanical engineering.

This Special Issue welcomes original high-quality submissions on engineering applications of CFD, with contributions on novel numerical methods or models, such as machine learning-aided CFD, high-fidelity CFD, turbulence and multiphase flow models, also being welcome.

The region of Xilingol League in Inner Mongolia exhibits typical sustained wind characteristics. To reveal the typical flow field behavior of transmission line conductors in sustained wind regions, this study takes the Xilingol League area as the research subject. First, based on regional meteorological data and investigations of transmission line, the characteristics of the sustained wind and typical conductor are analyzed. Two representative conductors, JLB40-120 and JL/G1A-400/35, are selected for the study. On this basis, two-dimensional numerical models of an actual stranded conductor cross-section and an equivalent smooth circular cylinder are established to conduct a comparative analysis of flow separation, wake evolution, Kármán vortex street formation, and pressure distribution characteristics for both a single conductor and a twin-bundled conductor under sustained wind. Furthermore, a three-dimensional flow field model is constructed to investigate the characteristics of streamline around the conductor and the spatial distribution of surface pressure. The results indicate that, compared to a single conductor structure, the twin-bundled conductor structure exhibits more significant wake interference between sub-conductors, resulting in more complex wake structures and pressure distributions. Compared with the equivalent smooth circular cylinder, the actual stranded conductor cross-section, due to its surface geometric irregularities and structural details, is more prone to inducing early boundary layer separation, leading to more complex wake evolution and asymmetric vortex shedding. The three-dimensional model further reveals that the flow around the conductor exhibits pronounced spatial characteristics, with both the wake vortex structures and surface pressure distribution showing non-uniform three-dimensional features. The results provide a reference for the analysis of wind-induced vibration mechanisms of transmission lines and the optimization of related structural designs under sustained wind conditions.

Nowadays various coupling strategies have been developed to combine the strengths of different numerical methods in computational fluid dynamics (CFD), among which the coupled algorithm of the lattice Boltzmann-finite volume method (LBM-FVM) has gained widespread attention. However, research on parallel optimization of LBM-FVM coupled solvers remains limited, mostly focused on independent solvers. In this work, we proposed a flexible framework and optimization schemes to explore the coordinated balance of accuracy-efficiency-hardware adaptability. First, we designed a processor layout strategy to address load imbalance and communication redundancy in the coupled solver. We then developed several parallelization techniques, including LBM restructuring, data reuse, and SIMD optimization for targeted kernels on the most advanced architecture of the Sunway series in China, namely SW26010P heterogeneous many-core processors, which provide hardware architectural advantages well suited for large-scale parallel computational fluid dynamics. Finally, the accuracy of the LBM-FVM coupling simulations was validated through benchmark simulations of 2D/3D lid-driven cavity flow. The results show that our LBM-FVM coupling solver can accurately capture flow characteristics, with vortex structures consistent with experimental data. Additionally, we achieved a 152× speedup for the LBM solver and a 126× speedup for the coupled simulation compared to the standalone FVM simulation on the New Sunway supercomputer system. Our approach marks a milestone in the field of LBM implementations and provides a promising future for coupled algorithms in CFD. Full article

This paper presents a numerical investigation into aerodynamic drag reduction by air jets for a realistic DrivAer estateback vehicle model. Numerical simulations are conducted based on Reynolds-Averaged Navier–Stokes equations with a shear stress transport k-ω turbulence model, for optimizing the drag reduction with seven individual rear slot jets and their combination. The results demonstrate that the jets located at the upper and lower edges of the rear end could achieve the highest individual drag reduction of up to 4.82%, by suppressing recirculation bubbles, delaying flow separation, and promoting pressure recovery. The jet positioned at the lower lateral side of vehicle base reduces the drag by 4.14% through the control of the underbody vortex. Moderate performance is observed for other individual jets within the wake flow. The underlying mechanisms are elucidated by detailed analyses of wake flow fields and rear-end surface pressure distributions. On this basis, optimal performance is obtained by a multi-jet combination, incorporating the best vertical jet and three better horizontal jets, which collectively yield a remarkable 11.80% drag reduction with high energy efficiency. This work confirms that the active flow control by the rear air jets can greatly improve the aerodynamic efficiency for realistic vehicles, providing a practical approach for drag reduction in modern automotive applications.
