Improved Marine Wind Farm Layout
Abstract: This work proposes a new marine wind farm layout. The new configuration is based on the hybridization of alternating lift-force and drag-force wind turbines. Lift-force wind turbines are characterized by a high output power and large dimensions, while drag-force wind turbines have moderate power output and reduced size. The proposed layout inserts the drag-force turbines in the free space the lift-force turbines leave, using the turbulent wind to generate power …

Analysis of new Floating Offshore Wind Turbine under drag force operation
Abstract: The goal of this paper is the study and analysis of a new type of floating offshore wind turbine (FOWT), which operates under drag force instead of lifting force as the conventional FOWT. We simulate the wind turbine operation modifying the pitch angle to faithfully reproduce the behavior when submitted to waves’ movement. The analysis of the wind turbine performance is developed in a model at laboratory scale to control …

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 …

A Computational Study of Lift and Drag Characteristics for NACA 4415 and NACA 2412 Aerofoils
Abstract: The performance of an aerofoil is crucial in designing wind turbine blades, aircraft wings, and other aerodynamic surfaces. This project presents a comparative analysis of two widely used aerofoil profiles, NACA 4415 and NACA 2412, to study their lift and drag characteristics under different flow regimes. The aerofoil geometries were developed using the NACA four-digit notation and modeled in ANSYS Design Modeler. Numerical simulations were conducted in ANSYS Fluent for …
