Comparative CFD Analysis of Major and Minor Aerodynamic Modifications for Tall Building Shapes under Wind Loading
Abstract: Aerodynamic performance of tall buildings is significant to structural safety and serviceability under wind. The major and minor aerodynamic changes of the tall building shape are compared with the computational fluid dynamics (CFD) simulation. The base model was a rectangle of 75 m × 75 m × 300 m. Various aerodynamic modifications of shapes were examined: circular, elliptical, tapered, twisted, rounded-corner, and chamfered-corner shapes. Simulations were carried out in the …

Aerodynamic Influences on Structures with Varied Plan Configurations
Abstract: The wind-induced effects on tall buildings demonstrate a level of unpredictability, attributed to the intricate influence of the building's plan shape on the distribution of wind loads. The oscillations experienced by tall structures, both longitudinally and laterally, are influenced by factors such as wind direction, building configuration, height, and structural characteristics. This investigation is centred around examining the impact of wind on tall buildings featuring diverse plan cross-sectional shapes. The …

AI-Assisted Optimization of Supersonic Airfoil Shapes Using CFD Coupling
Abstract: This paper presents a novel framework for optimizing supersonic airfoil geometries through integrated artificial intelligence and computational fluid dynamics coupling. Traditional gradient-based optimization methods for high-speed aerodynamic shapes suffer from computational expense and convergence difficulties in non-convex design spaces. The proposed methodology employs a deep neural network surrogate model trained on high-fidelity Reynolds-Averaged Navier-Stokes solutions to approximate aerodynamic performance metrics across the design space. A hybrid particle swarm-genetic algorithm searches …

Effect of Leading-Edge Roughness on the Aerodynamic Characteristics of the Wind Turbine blade
Abstract: Leading-Edge Roughness (LER) strongly dictates boundary layer transition and performance degradation on an airfoil operating at transitional Reynolds numbers, an aerodynamic regime where shear-layer stability mechanisms remain highly complex. The wind tunnel experiments were conducted to investigate the aerodynamic impacts of surface roughness applied over 25% of the chord of a NACA 0018 airfoil using two discrete roughness gradations. Surface roughness induces an early boundary layer trip, causing elevated section …
