Using the value simulation method, to leads the pylon to carry on the value wind tunnel test, processing obtains under the different operating mode flow field distribution, the wind pressure which in front of the guide post product label the behind surface and the main outrigger withstand and so on

By using numerical simulation method, numerical wind tunnel tests conducted by leading marks Tower, processing are flow field distribution in different conditions, leading marks signs before and after the walls and the main support beam subjected to wind pressure
