New Evaluation Technique for WTG Design Wind Speed Using a CFD-Model-Based Unsteady Flow Simulation with Wind Direction Changes
Table 2
Details of computational domain.
(i) Computational domain: 8,500 m square wind farm with the observation pole located at the center. The vertical height of the computational domain is approximately 2,900 m
(ii) Maximum elevation: 537 m
(iii) Minimum elevation: 0 m
(iv) Number of computational grids: 101 × 101 × 51
(v) Number of computational grids including those in the buffer zone: 121 × 121 × 51
(vi) Grid widths: 32 m ~ 769 m (horizontal direction); 1.7 m ~ 347 m (vertical direction)
(vii) Reynolds number: Re = 104 (based on the difference between the minimum and maximum elevations and the wind speed at the maximum elevation.)
