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 wi…

A method for evaluating relations of turbulent normal-stresses by experimental data over a wide range of Reynolds numbers
Hassan Nagib, Ivan Marusic
Recently, Nagib et al (2024} utilized indicator functions of profiles of the streamwise normal stress to reveal the ranges of validity, in wall distance and Reynolds number, for ea…
