High Reynolds number trends of centerline mean velocity and normal stress in pipe flow
Hassan Nagib, Lorenzo Lazzarini, Gabriele Bellani +1
The CICLoPE facility at the University of Bologna in Forli, Italy, is a unique facility that provides fully developed pipe flow up to Reynolds numbers of about of 50,000 wit…
Scaling of wall-pressure--velocity correlations in high Reynolds number turbulent pipe flow
Giulio Dacome, Lorenzo Lazzarini, Alessandro Talamelli +2
An experimental study was conducted in the CICLoPE long-pipe facility to investigate the correlation between wall-pressure and turbulent velocity fluctuations in the logarithmic re…
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-…
Sources and fluxes of scale-energy in the overlap layer of wall turbulence
A. Cimarelli, E. De Angelis, P. Schlatter +3
Direct Numerical Simulations of turbulent channel flows at friction Reynolds number 550, 1000, 1500, are used to analyse the turbulent production, transfer and dissipation mechanis…
