On the existence and characterization of extreme events in wind data
Garcia, Constantino; Lind, Pedro; Wächter, Matthias; Otero, Antonio; Peinke, Joachim (Conference object, 2019)We present evidence that quantitative definitions of extreme events in wind, so called gusts, may be flawed and unable to grasp true extreme situations of wind velocity in short time intervals. In particular, we show that ... -
Small scale structures of turbulence in terms of entropy and fluctuation theorems
Fuchs, Andre; Queiros, Silvio D.A.; Lind, Pedro; Girard, Alain; Bouchet, Freddy; Wächter, Matthias; Peinke, Joachim (Physical Review Fluids;5, 034602, Journal article; Peer reviewed, 2020-03-11)We present experimental evidence that, together with the integral fluctuation theorem, which is fulfilled with high accuracy, a detailed-like fluctuation theorem holds for large entropy values in cascade processes in ...
