Experiments have been conducted to assess the sizes and energy fractions of structure in fully developed turbulent pipe flow regime in two pipe facilities, ColaPipe at BTU Cottbus-Senftenberg, and CICLoPE at University of Bologna, for shear Reynolds

The present work aims at investigating the very large-scale structures of turbulent pipe flow in CICLoPE at high Reynolds numbers. According to recent studies, some open questions remain to be answered to identify accurate sizes of these turbulent st

In der Fahrzeugentwicklung spielt die Aerodynamik eine wichtige Rolle hinsichtlich der Optimierung der Fahrzeugform unter Berücksichtigung günstiger Beiwerte. Die Fahrzeuge werden in den Windkanälen unter idealen Bedingungen untersucht, bei denen
The energy efficiency of rail freight by means of reduced drag can be increased significantly by technical and operational measures. Previous studies have shown that optimizing the car sequence can result in a drag reduction by at least a factor of 2
