Abstract
Mittels PIV konnten erstmals groß-skalige Strukturen im turbulenten Geschwindigkeitsfeld bei thermischen Konvektionsströmungen nachgewiesen werden. Die PIV-Feldmessungen in sehr großen Lichtschnittebenen zeigen charakteristische Strömungswalzen in Abhängigkeit vom Aspektverhältnis (A) und Rayleigh-Zahl (Ra). Die Untersuchung dieser large-scale Strukturen erfolgte am zylindrischen Rayleigh-Bénard-Großexperiment "Ilmenauer Fass" und an der rechteckigen Konvektionszelle "ILKA", wobei Luft als Arbeitsfluid eingesetzt wurde.
