On that basis, a new blade shape called as combined blade for Guiding VAWT was proposed and numerical investigation was complemented on its aerodynamic performance by CFD (Computational Fluid Dynamics) technique.
CFD (Computational Fluid Dynamics) technique is introduced to numerically investigate the aerodynamic performance of this Guiding VAWT with combined blade.
NUMERICAL MODEL The Guiding VAWT proposed in this paper is essentially a two dimensional structure, so the two dimensional domain for CFD simulation is chosen.
The grids for this CFD calculation is unstructured mesh inside the VAWT while in the extension domain, structure meshes are adopted to reduce the total grid number.
Followings are the prescribed boundary conditions: Inlet: Uniform velocity of the coming flow; Outlet: Ambient pressure of atmosphere; Walls: No-Slip conditions; The whole CFD calculations are complemented by commercial CFD software Fluent and the mesh generation is by its component -GAMBIT.
