Analysis of the Output Power in Offshore Bladeless Vibrational Wind Turbines

By Diego Piqueras Sanz, Carlos Armenta-Déu, Jorge Contreras, Matilde Santos

Abstract: This work focuses on studying and analyzing the power generation in offshore bladeless vibrational wind turbines. In previous work, we developed detailed research about the vibrational wind turbine design and configuration; in this new work, we analyze the energy supply from this type of turbine to achieve a better understanding of the behavior and potential of bladeless vibrational wind turbines (BVWT) as an additional power source in offshore wind farms. …

Vibrational Wind Turbine Design

By Carlos Armenta-Déu, Ignacio Madrazo, Jorge Contreras, Matilde Santos

Abstract: This work focuses on the study and analysis of bladeless wind turbines (BWT) as an alternative to operating vertical-axis wind turbines (VAWT) and horizontal-axis wind turbines (HAWT). A mathematical analysis of the BWT oscillation under wind force allows the development of specific mathematical expressions for the oscillation speed and BWT mast displacement at any height. The oscillation movement is submitted to a Strouhal constant number condition, resulting in an algorithm …

Effect of Leading-Edge Roughness on the Aerodynamic Characteristics of the Wind Turbine blade

By Santhosh Sabapathy

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 …
