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…
Reconsiderations about inner layer of wall-bounded flows
Hassan Nagib
Following recent evidence that even ZPG boundary layers do not exhibit a purely logarithmic extended overlap region, reconsideration of recently advanced logarithmic plus linear ex…
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…
Higher DNS-resolution requirements for expanded overlap region and confirmation of a convergence criterion
Sergio Hoyas, Ricardo Vinuesa, Peter Schmid +1
Direct numerical simulations (DNS) stand out as formidable tools in studying turbulent flows. Despite the fact that the achievable Reynolds number remains lower than those availabl…
