Turbulente Strömung im Windkanal

"I became interested in turbulent liquid and gas flows at the end of the thirties. From the very beginning it was clear that the theory of random functions of many variables (random fields), whose development only started at that time, must be the underlying mathematical technique. Moreover, I soon understood that there was little hope of developing a pure, closed theory, and because of the absence of such a theory the investigation must be based on hypotheses obtained by processing experimental data." - A.N. Kolmogorov 1985

Der turbulente Character der Windenergie

Patrick Milan, Matthias Wächer und Joachim Peinke beschreiben in einem Artikel in der Fachzeitschrift Physical Review Letters, dass der Energiewandlungsprozess auf kleinen Zeitskalen im Sekundenbereich komplexen Mustern mit multi-fraktalen Skalengesetzen folgt, welche der Theorie zur Turbulenz von A. N. Kolmogorov aus dem Jahre 1962 entsprechen.
