"It might be galloping..."

Aeroelasticity is like a kind of black hole ... the darkest source of infinite curiosity across Universe.
"Lies are like flies, they fly everywhere and pose where the sweet smell of curiosity is strongest" (Pio Rossi). And those who unscrupulously plagiarize are "vagrants of knowledge."
We continue studying and learning every day… thanks to a lot of people and colleagues who share their achievements and time, even during these hazardous times.
And, paraphrasing the discovers of Cygnus X-1… , “it might be galloping”.
Happy 2020 Easter to everyone!

"Eppur si mouve"

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.
