Our Group (GIFD, Department of Energy, University of Oviedo) is developing a new method to calculate the structure of the Photovoltaic Solar Trackers against the effect of wind. Due to the lack of knowledge (there is only a little scientific knowledge because this is a very new and recent issue) we found in the national and international standard and codes, a few of laboratories and wind tunnels all over the world are trying to find out what is the aeroelastic mechanism which causes such a disaster called torsional galloping or 1DOF flutter.
We leave herein below one of our 2D CFD approaches, showing a real case of a single axis solar tracker placed at 30º of initial tilt angle panel and oscillating at 1,2 Hz and moderate amplitudes, under wind speed of 20 m/s.
