Research on Wind Flow Control by Windbreak Fence for a Large Radio Telescope Site Based on Numerical Simulations

Figure 12

The reducing coefficient of the extreme condition of the site. “NS40-0.5 H” and “NS33−0.5 H” are the simulation results of Section 2.6. “A” is the actual terrain model. “33” is porosity. “0.5 H” and “0.8 H” are different heights relative to the ground. The antenna position is 6.7 H behind the fence.
