Abstract
Die auftriebsinduzierte Sekundärströmung in sinusförmig beheizten Rohrsegmenten wird mithilfe der direkten numerischen Simulation (DNS) für eine Reynolds-Zahl von Re = 4328, eine Prandtl-Zahl von Pr = 0.71 und verschiedene Grashof-Zahlen turbulenzstatistisch erklärt und mit der Sekundärströmung in gekrümmten Rohren verglichen.
