Kurzbeschreibung (Abstract)
Rotating turbulent flows play more a major role in engineering applications such as in gas turbine blade passages, pumps and rotating heat exchangers to name only a few. In these cases secondary flows are induced caused by centrifugal or Coriolis forces. Investigations of [4] using symmetry theory showed that there is a new turbulent scaling law related to the turbulent channel flow rotating about the mean flow direction. Figure 1 depicts the flow geometry. The flow has several common features with the classical rotating channel flow rotating about the spanwise direction [2] but also has some different characteristics. The induction of a mean velocity in x3-direction [5] is the most obvious difference compared to the classical case. In this paper the results of a Lie group analysis and a corresponding DNS at Reynolds number Re=180 for different rotation rates are presented and discussed. The main objective of the present paper is to validate the results from the Lie group analysis.
