cfdof-workbench: verify antenna wind load

Postby thschrader » Fri Mar 20, 2020 6:09 pm

The antenna manufacturer COMMSCOPE has done some windtunnel
testing for antennas including cfd-simulations:

Our own cfd-calculation (Axians) gives a good accordance to the commscope results.
Error only 3%.
Calculation at 150 km/h windspeed with k-omega turbulence model.
Antenna type EGYHHTT-65B-R6.
(turbulence intensity 15% in far field according to Eurocode manuals)
Next step: calculating wind-forces on antenna clusters (one is not enough for cell-phone communication)
Thanks to the cfdof-wb developers!
