In this study, an unsteady aerodynamic simulation is performed to realize the influences of platform surge motion on the aerodynamic performance of a high capacity offshore floating wind turbine. A dynamic model with pitch angle control system is utilized to propose a more realistic model of wind turbine and also achieve the rated condition of the rotor. The transient effect of platform surge m...

This study analyses for the first time observed surface mean wind speed (SWS) and gusts over Iberian Peninsula (IP) in frequency domain 1961–2019, with goal of exploring sources predictability interannual decadal scales. The main result is high significant correlation between winds stratospheric polar vortex periods close to 1 year a lag about 2–3 months respect antiphase, that is, negative whi...

CNC turning is widely used as a manufacturing process through which unwanted material is removed to get the high degree of surface rough. In this research article, Taguchi technique was coupled with grey relation analysis (GRA) to optimize the turning parameters for simultaneous improvement of productivity, average surface roughness (Ra), and root mean square roughness (Rq).Taguchi technique L2...
