Embodiment Construction
[0040] The present invention will be further described in detail with the accompanying drawings and specific embodiments below, which are explanations rather than limitations of the present invention.
[0041] In order to verify the validity of the wake calculation method proposed by the present invention, the wake velocity distribution calculated by this method under different working conditions is compared with the large eddy simulation results reported in the literature and the wind tunnel experimental results, mainly comparing the wake expansion coefficient and velocity deficit distribution under different surface roughness and atmospheric stability conditions. The example data of the comparison of the present invention comes from reference [1].
[0042] The present invention adopts figure 2 The control body shown, in accordance with figure 1 The steps shown build the wake calculation method. exist figure 2 in, U ∞ is the incoming flow velocity, U w is the velocity...
