Aerodynamic Optimization of UAV Wings Using Machine Learning
Abstract: Unmanned Aerial Vehicles (UAVs) are increasingly deployed across defense, transportation, agriculture, and environmental monitoring, demanding improved aerodynamic efficiency to enhance endurance, stability, and payload capacity. Traditional aerodynamic optimization approaches, relying on computational fluid dynamics (CFD) simulations and wind tunnel experiments, are often time-consuming and computationally expensive. This study proposes a machine learning (ML)-driven framework for the aerodynamic optimization of UAV wing geometries, aiming to significantly reduce design cycles while improving …

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 …

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 …

Optimizing Mango Harvest Timing in the Nasik Region (Maharashtra, India) by CNNs (Residual Network 101)
Abstract: The determination of optimal harvest timing is one of the most critical decisions in mango production, directly affecting postharvest quality, market value, transportation resilience, and export readiness. In regions such as Nashik, Maharashtra—one of India’s major fruit- producing belts—the climatic variability, cultivar differences, monsoon patterns, and market- driven pressures make accurate harvest timing essential. Traditional maturity assessment relies on subjective visual inspection, specific gravity, or destructive testing, each of which …
