This article introduces a new wind turbine, called resistance type vertical axial wind turbine (VAWT) with soft blades. The blades of the new turbine resist the wind and collect the power along the wind direction, while canceled the resistance against the wind direction. The new work mechanism was conceived to improve the aerodynamic performances of traditional VAWT. To prove the above supposing,...
Vertical axis water turbine (hereafter VAWT) is the common investigated equipment in tidal streams turbine generator system. In this paper, the flow fields around a VAWT were numerical simulated with emphasis on the hydrodynamic performance of VAWT. The simulations were undertaken with the Computational Fluid Dynamics (CFD) software FLUENT 6.2 using the sliding meshes controlled by user-defined functions...
