چکیده
The paper deals with the dynamic analysis of a tri-floater 1 MW offshore Vertical Axis Wind Turbine (VAWT) placed at its centroid. Six line catenary mooring system was used for controlling horizontal movement floater. floater modeled as rigid body six degrees freedom. Mass, damping and hydrostatic stiffness were calculated by using stability condition. aerodynamic load on via stream tube theory. Wave profile Airy’s wave theory followed use Morison’s equation to determine inertial drag forces A computer program developed MatLab package force calculation including wind excitations analysis. Newmark - beta method performed these analyses. motion solved in time domain. Restoring lines each instant based cable profile. Responses VAWT different sea conditions analyzed. It proven that surge, heave pitch are predominant motions straight (00) wave. These also analyzed waves inclinations their responses considered compared.

Scaling of Vertical Axis Wind Turbine Dynamic Stall
Vertical axis wind turbines (VAWT) are an alternative to horizontal axis wind turbines (HAWT) for wind and tidal energy harvesting applications. Studies of vertical axis wind turbines have heavily invested in understanding the behaviour of the complete turbine, but often with only cursory assessment of the contributions of unsteady aerodynamics of individual blades. This paper experimentally ex...
متن کاملAerodynamic Analysis of a Helical Vertical Axis Wind Turbine
Vertical axis wind turbines (VAWTs) are gradually receiving more and more interest due to their lower sensitivity to the yawed wind direction. Compared with straight blades VAWT, blades with a certain helicity show a better aerodynamic performance and less noise emission. Nowadays computational fluid dynamics technology is frequently applied to VAWTs and gives results that can reflect real flow...
