Figure 4: Wind shear velocity over the array of fences.
Each fence has height hf = 1.25 m and porosity Φ = 40%, while the spacing between the fences, L, is varied according to the legend. The wind shear velocity at the inlet is u*0 = 0.4 m/s. (a) Shear velocity profile with distance downwind and (b) maximal values as a function of the fence number, that is between fence i − 1 and i, from second fence (i = 1) to the last one (i = 9).
