Statistics, plumes and azimuthally traveling waves in ultimate Taylor-Couette turbulent vortices
Andreas Froitzheim, Rodrigo Ezeta, Sander G. Huisman +4
In this paper, we experimentally study the influence of large-scale Taylor rolls on the small-scale statistics and the flow organization in fully turbulent Taylor-Couette flow {for…
Angular momentum transport and flow organisation in Taylor-Couette flow at radius ratio of
Andreas Froitzheim, Sebastian Merbold, Rodolfo Ostilla-Mónico +1
We experimentally and numerically investigate the angular momentum transport in turbulent Taylor-Couette flow for independently rotating cylinders at a small radius ratio of $η=0.3…
One-Dimensional Flow Spectra and Cumulative Energy from Two Pipe Facilities
E. -S. Zanoun, Emir Öngüner, C. Egbers +2
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-…
Dielectrophoretic force-driven convection in annular geometry under Earth's gravity
Torsten Seelig, Antoine Meyer, Philipp Gerstner +5
Context: A radial temperature gradient together with an inhomogeneous radial electric field gradient is applied to a dielectric fluid confined in a vertical cylindrical annulus ind…
